What are the symptoms of Focal dermal hypoplasia ? | What are the signs and symptoms of Focal dermal hypoplasia? Focal dermal hypoplasia is usually evident from birth and primarily affects the skin, skeleton, eyes, and face. The signs and symptoms of vary widely, although almost all affected individuals have skin abnormalities. Some of the skin findings include streaks of very thin skin (dermal hypoplasia), yellowishpink nodules of fat under the skin, areas where the top layers of skin are absent (cutis aplasia), telangiectases, and streaks of slightly darker or lighter skin. These skin features can cause pain, itching, irritation, or lead to skin infections. With age, most develop wartlike growths, called papillomas, around the nostrils, lips, anus, and female genitalia. They may also be present in the throat, specifically in the esophagus or larynx, and can cause problems with swallowing, breathing, or sleeping. Other features include small, ridged fingernails and toenails as well as sparse, brittle or absent scalp hair. The skeleton is usually affected as well. Many individuals have hand and foot abnormalities, including missing fingers or toes (oligodactyly), webbed or fused fingers or toes (syndactyly), and a deep split in the hands or feet with missing fingers or toes and fusion of the remaining digits (ectrodactyly). Xrays can show streaks of altered bone density, called osteopathia striata, which usually do not cause symptoms. Eye abnormalities are common and can include microphthalmia and anopthalmia as well as problems with the tear ducts. The retina or the optic nerve can also be incompletely developed, which can result in a gap or split in these structures (coloboma). Some of these eye abnormalities do not impair vision, while others can lead to low vision or blindness. People with focal dermal hypoplasia often have distinctive, but subtle facial features such as a pointed chin, small ears, notched nostrils, and a slight difference in the size and shape of the right and left sides of the face (facial asymmetry). Some individuals may have a cleft lip and/or palate. About half of those with focal dermal hypoplasia have teeth abnormalities of their teeth, especially of the enamel (the hard, white material that forms the protective outer layer of each tooth). Less commonly, kidney and gastrointestinal abnormalities are present. The kidneys may be fused together, which can lead to kidney infections. The main gastrointestinal abnormality that is seen is an omphalocele. The Human Phenotype Ontology provides the following list of signs and symptoms for Focal dermal hypoplasia. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
Is Focal dermal hypoplasia inherited ? | How is this condition inherited? Focal dermal hypoplasia is caused by mutations in the PORCN gene and is inherited in an Xlinked dominant manner. Many cases of focal dermal hypoplasia result from a new mutation and occur in people with no history of the disorder in their family For a woman affected with focal dermal hypoplasia, the theoretical risk of passing the mutation to each of her offspring is 50%; however, many males with this condition do not survive. In addition, there are cases in which a woman may have the focal dermal hypoplasia mutation in some but not all of her egg cells, a condition known as germline mosaicism. In this case the risk of passing along the mutation may be as high as 50% depending on the level of mosaicism. Males with focal dermal hypoplasia typically have the mutation in some but not all of their cells. The risk that a male with FDH will pass the condition on to his daughters may be as high as 100%; men do not pass this condition on to their sons. We recommend discussing specific concerns with a genetics professional, who can help you understand how this condition might be inherited in your family.

What is (are) Dihydropteridine reductase deficiency ? | Dihydropteridine reductase deficiency (DHPR) is a severe form of hyperphenylalaninemia (high levels of the amino acid phenylalanine in the blood) due to impaired renewal of a substance known as tetrahydrobiopterin (BH4). Tetrahydrobiopterin normally helps process several amino acids, including phenylalanine, and it is also involved in the production of neurotransmitters. If little or no tetrahydrobiopterin is available to help process phenylalanine, this amino acid can build up in the blood and other tissues and the levels of neurotransmitters (dopamine, serotonin) and folate in cerebrospinal fluid are also decreased. This results in neurological symptoms such as psychomotor delay, low muscle tone (hypotonia), seizures, abnormal movements, too much salivation, and swallowing difficulties. DHPR deficiency is caused by mutations in the QDPR gene. It is inherited in an autosomal recessive manner. Treatment should be started as soon as possible and includes BH4 supplementation usually combined with a diet without phenylalanine, folate supplementation, and specific medications to restore the levels of neurotransmitters in the brain. |

What is (are) Plasminogen activator inhibitor type 1 deficiency ? | Plasminogen activator inhibitor type 1 (PAI1) deficiency a rare disorder that causes premature breakdown of blood clots and a moderate bleeding syndrome. While spontaneous bleeding is rare, moderate hemorrhages of the knees, elbows, nose and gums may be triggered by mild trauma. In females, menstrual bleeding is often severe. Prolonged bleeding after surgery is also common. PAI1 deficiency is caused by homozygous or compound heterozygous mutation in the SERPINE1 gene. Fibrinolysis inhibitors, including epsilonaminocaproic acid and tranexamic acid, are usually effective in treating and preventing bleeding episodes. |

What is (are) Meningioma ? | Meningiomas originate in the meninges, the membranes that surround the brain and spinal cord. Most meningiomas are benign, though a minority of meningiomas can be classified as atypical or malignant. Though rare, malignant meningiomas can be highly aggressive. However, even benign meningiomas can cause problems if their growth affects the neighboring areas of the brain. Though most meningiomas grow slowly, there is no way to predict the rate of growth for a particular meningioma or to know how long a specific meningioma was growing before it was diagnosed. Signs and symptoms can vary but may include seizures, headaches, weakness in the arms and legs, and vision loss. Sometimes memory loss, carelessness, and unsteadiness are the only symptoms. |
What are the treatments for Meningioma ? | How might meningiomas be treated? The treatment varies depending on the location of the meningioma and the symptoms caused by the tumor. Careful observation is sometimes the best course of action for people with a meningioma. When treatment is necessary, surgery and radiation are the most common forms of treatment. Radiation may be used if the meningioma cannot be operated on or if the meningioma is only partially removed by surgery. Radiation may also be used in cases of malignant, atypical, or recurrent tumors. Other treatments that have been tried or are being explored include hydroxyurea, epidermal growth factor receptor inhibitors, plateletderived growth factor receptor inhibitors, vascular endothelial growth factor inhibitors, immunotherapy to stimulate the immune system, and somatostatin analogs which prevent the release of growth hormones. |

What is (are) Rett syndrome ? | Rett syndrome is a progressive, neurodevelopmental condition that primarily affects girls. Affected girls appear to have normal psychomotor development during the first 6 to 18 months of life, followed by a developmental "plateau," and then rapid regression in language and motor skills. Additional signs and symptoms may include repetitive, stereotypic hand movements; fits of screaming and inconsolable crying; autistic features; paniclike attacks; teeth grinding (bruxism); episodic apnea and/or hyperpnea; gait ataxia and apraxia; tremors; seizures; and slowed head growth. Some people have an atypical form of Rett syndrome that may be more mild or more severe. Classic Rett syndrome is most commonly caused by mutations in the MECP2 gene and is usually inherited in an Xlinked dominant manner. The vast majority of cases are not inherited from a parent, but are due to a new mutation in the affected person. Treatment mainly focuses on the specific signs and symptoms of the condition. |

What causes Rett syndrome ? | What causes Rett syndrome? Rett syndrome is typically caused by changes (mutations) in the MECP2 gene. This gene provides instructions for making a protein (MeCP2) needed for the development of the nervous system and normal brain function. Mutations in the MECP2 gene that cause Rett syndrome can change the MeCP2 protein or result in the production of too little protein, which appears to disrupt the normal function of neurons and other cells in the brain. Several conditions caused by changes in other genes (such as FOXG1 syndrome) have overlapping signs and/or symptoms of Rett syndrome. These conditions were once thought to be variant forms of Rett syndrome, but are now usually considered to be separate disorders. |
Is Rett syndrome inherited ? | Is Rett syndrome inherited? Although Rett syndrome is a genetic disorder, less than 1 percent of recorded cases are inherited or passed from one generation to the next. Most cases are sporadic, which means the mutation occurs randomly, and are not inherited. A few families have been described with more than one affected family member. These cases helped researchers determine that Rett syndrome has an Xlinked dominant pattern of inheritance. A condition is considered Xlinked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition. |

What is (are) Chiari malformation ? | Chiari malformations are structural defects in the cerebellum, the part of the brain that controls balance. When the indented bony space at the lower rear of the skull is smaller than normal, the cerebellum and brainstem can be pushed downward. The resulting pressure on the cerebellum can block the flow of cerebrospinal fluid (the liquid that surrounds and protects the brain and spinal cord) and can cause a range of symptoms including dizziness, muscle weakness, numbness, vision problems, headache, and problems with balance and coordination. Treatment may require surgery. Many patients with the more severe types of Chiari malformations who undergo surgery see a reduction in their symptoms and/or prolonged periods of relative stability, however paralysis is generally permanent despite surgery. There are four types of Chiari malformations. The types tend to correspond with the degree of severity, with type 1 being the most common and least severe. Some people with type 1 have no symptoms and do not require treatment. Chiari malformation type 1 Chiari malformation type 2 Chiari malformation type 3 Chiari malformation type 4 |

What is (are) Fowler's syndrome ? | Fowlers syndrome is characterized by urinary retention associated with abnormal electromyographic activity in young women in the absence of overt neurologic disease. Some women with this syndrome have polycystic ovaries as well. |
What are the symptoms of Fowler's syndrome ? | What are the signs and symptoms of Fowler's syndrome? Fowlers syndrome typically occurs in premenopausal women (often in women under 30 years of age) who are unable to void for a day or more with no feeling of urinary urgency, but with increasing lower abdominal discomfort. The Human Phenotype Ontology provides the following list of signs and symptoms for Fowler's syndrome.

What causes Fowler's syndrome ? | What causes Fowlers syndrome? The cause of Fowler's syndrome is not known. The association of Fowlers syndrome and polycystic ovaries in some patients raises the possibility that the syndrome is linked in some way to impaired muscle membrane stability, owing possibly to a hormonal abnormality. The involvement of such a hormonal abnormality may also explain why it primarily affects premenopausal women. |
How to diagnose Fowler's syndrome ? | How is Fowlers syndrome diagnosed? Diagnosis of Fowlers syndrome involves ruling out neurological or laboratory features that would support a diagnosis of a underlying neurological disease, and identification of a bladder capacity of over 1 liter with no sensation of urgency. Also in Fowlers syndrome, analysis of the striated muscle of the urethral sphincter using concentric needle electrode examination reveals a fairly unique electromyographic (EMG) abnormality. This EMG abnormality is found in association with the urethral sphincter (group of muscles which surround the urinary passage below the bladder), and consists of a type of activity that would be expected to cause inappropriate contraction of the muscle (i.e., impair sphincter relaxation). |
What are the treatments for Fowler's syndrome ? | How might Fowlers syndrome be treated? The urinary incontinence caused by Fowlers syndrome may be treated by sacral neuromodulation therapy. The success rate for treatment of Fowlers syndrome with neuromodulation has been estimated to be around 70%, even in women who have been experiencing symptoms for a while. Neuromodulation therapy involves the stimulation of nerves to the bladder leaving the spine. The FDA has approved a device called InterStim for this purpose. Your doctor will need to test to determine if this device would be helpful to you. The doctor applies an external stimulator to determine if neuromodulation works in you. If you have a 50 percent reduction in symptoms, a surgeon will implant the device. Although neuromodulation can be effective, it is not for everyone. The therapy is expensive, involving surgery with possible surgical revisions and replacement. Other treatments that have been tried with little success include hormonal manipulation, pharmacologic therapy, and injections of botulinum toxin. |
What is (are) Mikulicz disease ? | Mikulicz disease is a chronic condition characterized by the abnormal enlargement of glands in the head and neck, including those near the ears (parotids), around the eyes (lacrimal), and around the mouth (salivary). The tonsils and other glands in the soft tissue of the face and neck can also be affected. Although this condition is usually benign, it always occurs in association with another underlying disorder such as tuberculosis, leukemia, syphilis, Hodgkin's disease, Sjogren syndrome, or systemic lupus erythematosus. People with Mikulicz disease are at greater risk of developing lymphomas. Some people may experience recurring fevers accompanied by dry eyes, diminished tear production, and inflammation of various parts of the eyes (uveitis). The exact cause of Mikulicz syndrome is unknown. But some researchers believe that it should be considered a form of Sjogren syndrome. |
What is (are) Focal dystonia ? | Focal dystonia is a movement disorder that is localized to a specific part of the body. The dystonias are a group of movement problems characterized by involuntary, sustained muscle contractions, tremors, and other uncontrolled movements. Focal taskspecific dystonia, or FTSD, interferes with the performance of particular tasks, such as writing, playing a musical instrument, or participating in a sport. Additionally, FTSD has been reported in tailors, shoemakers, hair stylists, and people who frequently type or use a computer mouse. While the abnormal movements associated with focal dystonia are usually painless, they can cause high levels of anxiety. The causes of focal dystonia are unknown, although the disorder likely results from a combination of genetic and environmental factors. It is possible that the different forms of FTSD have different underlying causes. Researchers have found that at least some cases are related to malfunction of the basal ganglia, which are structures deep within the brain that help start and control movement. Most cases of focal dystonia are sporadic, which means they occur in people with no history of the condition in their family. However, at least 10 percent of affected individuals have a family history which seems to follow an autosomal dominant pattern of inheritance. |
What are the symptoms of Focal dystonia ? | What are the signs and symptoms of Focal dystonia? The Human Phenotype Ontology provides the following list of signs and symptoms for Focal dystonia. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What is (are) Hypophosphatemic rickets ? | Hypophosphatemic rickets (previously called vitamin Dresistant rickets) is a disorder in which the bones become painfully soft and bend easily, due to low levels of phosphate in the blood. Symptoms usually begin in early childhood and can range in severity. Severe forms may cause bowing of the legs and other bone deformities; bone pain; joint pain; poor bone growth; and short stature. In some affected babies, the space between the skull bones closes too soon (craniosynostosis). This sometimes results in developmental abnormalities. Hypophosphatemic rickets is almost always inherited and may be caused by changes (mutations) in any of several genes. Most commonly it is due to the PHEX gene and inherited in an Xlinked dominant manner. Less commonly it is inherited in an Xlinked recessive manner (often called Dent disease); autosomal dominant manner; or autosomal recessive manner. Treatment involves taking phosphate and calcitriol in order to raise phosphate levels in the blood and promote normal bone formation. |
What are the symptoms of Hypophosphatemic rickets ? | What are the signs and symptoms of Hypophosphatemic rickets? The symptoms of hypophosphatemic rickets usually begin in infancy or early childhood. Specific symptoms and severity can vary greatly among affected children. The condition can be so mild that there are no noticeable symptoms, or so severe that it causes bowing of the legs and other bone deformities; bone pain; joint pain; and short stature. Other symptoms may include premature closure of the skull bones in babies (craniosynostosis); limited joint movement; and dental abnormalities. If left untreated, symptoms worsen over time.

What causes Hypophosphatemic rickets ? | What causes hypophosphatemic rickets? Hypophosphatemic rickets is almost always hereditary and may be caused by mutations in any of several genes. The specific gene involved determines the way it is inherited. Most commonly, it is caused by a mutation in the PHEX gene. Other genes that can be responsible for the condition include the CLCN5, DMP1, ENPP1, FGF23, and SLC34A3 genes. The genes associated with hereditary hypophosphatemic rickets are involved in keeping a proper balance of phosphate in the body. Many of these genes directly or indirectly regulate a protein that normally inhibits the kidneys' ability to reabsorb phosphate into the blood. Mutations affecting the function of these genes increase the production (or reduce the breakdown) of the protein, causing the protein to be overactive. The overactivity of the protein reduces phosphate reabsorption by the kidneys, leading to the features of the condition. Rarer, sporadic, acquired cases are sometimes associated with benign (noncancerous) mesenchymal tumors that decrease resorption of phosphate. |
Is Hypophosphatemic rickets inherited ? | How is hypophosphatemic rickets inherited? Hypophosphatemic rickets is most often inherited in an Xlinked dominant manner. This means that the gene responsible for the condition is located on the X chromosome, and having only one mutated copy of the gene is enough to cause the condition. Because males have only one X chromosome (and one Y chromosome) and females have two X chromosomes, Xlinked dominant conditions affect males and females differently. Both males and females can have an Xlinked dominant condition. However, because males don't have a second, working copy of the gene (as females do), they usually have more severe disease than females. If a father has the mutated Xlinked gene: all of his daughters will inherit the mutated gene (they will all receive his X chromosome) none of his sons will inherit the mutated gene (they only inherit his Y chromosome) If a mother has the mutated Xlinked gene, each of her children (both male and female) has a 50% chance to inherit the mutated gene. Less commonly, hypophosphatemic rickets is inherited in an Xlinked recessive, autosomal dominant, or autosomal recessive manner. |

What is (are) Hereditary fructose intolerance ? | Hereditary fructose intolerance (HFI) is a metabolic disease caused by the absence of an enzyme called aldolase B. In people with HFI, ingestion of fructose (fruit sugar) and sucrose (cane or beet sugar, table sugar) causes severe hypoglycemia (low blood sugar) and the build up of dangerous substances in the liver. HFI may be relatively mild or a very severe disease. The condition is caused by mutations in the ALDOB gene. It is inherited in an autosomal recessive pattern. Treatment involves eliminating fructose and sucrose from the diet. In the severe form, eliminating these sugars from the diet may not prevent progressive liver disease. |
What are the symptoms of Hereditary fructose intolerance ? | What are the signs and symptoms of Hereditary fructose intolerance? The symptoms of HFI include: Poor feeding as a baby Irritability Increased or prolonged neonatal jaundice Vomiting Convulsions Excessive sleepiness Intolerance for fruits Avoidance of fruits and fructose/sucrosecontaining foods Doing well after eating foods without fructose/sucrose The early symptoms of fructose intolerance may resemble those of galactosemia: irritability, jaundice, vomiting, convulsions and an enlarged liver and spleen. Later problems relate more to liver disease. The Human Phenotype Ontology provides the following list of signs and symptoms for Hereditary fructose intolerance. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Hereditary fructose intolerance ? | What causes hereditary fructose intolerance (HFI)? HFI is caused by alterations (mutations) in the ALDOB gene. This gene provides instructions for making an enzyme called aldolase B. This enzyme is primarily found in the liver and is involved in the breakdown of fructose into energy. Mutations in the ALDOB gene reduce the function of the enzyme, impairing its ability to metabolize fructose. This causes a toxic buildup of fructose1phosphate in liver cells, which results in the death of liver cells over time. |
Is Hereditary fructose intolerance inherited ? | How is hereditary fructose intolerance (HFI) inherited? HFI is inherited in an autosomal recessive manner, which means alterations (mutations) are present in both copies of the ALDOB gene. The parents of an individual with HFI each carry one copy of the mutated gene, but they typicaly do not show signs and symptoms of the condition. |
What are the treatments for Hereditary fructose intolerance ? | How is hereditary fructose intolerance (HFI) treated? Complete elimination of fructose and sucrose from the diet is an effective treatment for most people, although this can be challenging. More information on treatment for HFI is available from the HFI Laboratory at Boston University at the following link. This page includes information on what people with HFI can and cannot eat. http://www.bu.edu/aldolase/HFI/treatment/ Additional information on foods to avoid if you have HFI is available from the Mayo clinic. http://www.mayoclinic.com/health/fructoseintolerance/AN01574 |
What is (are) Carnitine-acylcarnitine translocase deficiency ? | Carnitineacylcarnitine translocase deficiency is a condition that prevents the body from converting certain fats called longchain fatty acids into energy, particularly during periods without food (fasting). Carnitine, a natural substance acquired mostly through the diet, is used by cells to process fats and produce energy. People with this disorder have a faulty transporter that disrupts carnitine's role in processing longchain fatty acids. Carnitineacylcarnitine translocase deficiency is a type of fatty acid oxidation disorder. There are two forms of carnitineacylcarnitine translocase deficiency. The most common type happens in newborns. A milder, less common type happens in older infants and children. |
What are the symptoms of Carnitine-acylcarnitine translocase deficiency ? | What are the signs and symptoms of Carnitineacylcarnitine translocase deficiency? The signs of carnitineacylcarnitine translocase deficiency usually begin within the first few hours after birth. Seizures, an irregular heartbeat (arrhythmia), and breathing problems are often the first signs of this disorder. This disorder may also result in an extremely low level of ketones, which are products of fat breakdown that are used for energy. Low blood sugar (hypoglycemia) is another major feature. Together these signs are called hypoketotic hypoglycemia, which can result in unconsciousness and seizures. Other signs that are often present include excess ammonia in the blood (hyperammonemia), an enlarged liver (hepatomegaly), heart abnormalities (cardiomyopathy), and muscle weakness. This disorder can cause sudden infant death. Children with the mild type of carnitineacylcarnitine translocase deficiency usually start having symptoms before age three. They are at risk to have episodes of metabolic crisis, but usually do not have heart problems. The Human Phenotype Ontology provides the following list of signs and symptoms for Carnitineacylcarnitine translocase deficiency. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
What causes Carnitine-acylcarnitine translocase deficiency ? | What causes carnitineacylcarnitine translocase deficiency? Carnitineacylcarnitine translocase deficiency occurs when an enzyme, called "carnitineacylcarnitine translocase" (CAT), is either missing or not working properly. This enzyme's job is to help change certain fats in the food we eat into energy. It also helps to break down fat already stored in the body. Energy from fat keeps us going whenever our bodies run low of their main source of energy, a type of sugar called glucose. Our bodies rely on fat for energy when we don't eat for a stretch of time like when we miss a meal or when we sleep. When the CAT normal enzyme is missing or not working well, the body cannot use fat for energy, and must rely solely on glucose. Although glucose is a good source of energy, there is a limited amount available. Once the glucose has been used up, the body tries to use fat without success. This leads to low blood sugar, called hypoglycemia, and to the build up of harmful substances in the blood. |
Is Carnitine-acylcarnitine translocase deficiency inherited ? | How is carnitineacylcarnitine inherited? Carnitineacylcarnitine translocase deficiency is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. |
How to diagnose Carnitine-acylcarnitine translocase deficiency ? | Is there genetic testing available for carnitineacylcarnitine translocase deficiency? Genetic testing for carnitineacylcarnitine translocase deficiency can be done on a blood sample. Genetic testing, also called DNA testing, looks for changes in the pair of genes that cause carnitineacylcarnitine translocase deficiency. In some affected children, both gene changes can be found. However, in other children, neither or only one of the two gene changes can be found, even though we know they are present. DNA testing is not necessary to diagnose carnitineacylcarnitine translocase deficiency, however, it can be helpful for carrier testing or prenatal diagnosis. |
What are the treatments for Carnitine-acylcarnitine translocase deficiency ? | How might carnitineacylcarnitine translocase deficiency be treated? Although there is no standard treatment plan for carnitineacylcarnitine translocase deficiency, there are treatments that have been found to be helpful in the management of this condition. Certain treatments may be helpful for some children but not others. When necessary, treatment are usually needed throughout life. Children with carnitineacylcarnitine translocase deficiency should be followed by a metabolic doctor and a dietician in addition to their primary doctor. Aggressive treatment of hypoglycemia, hyperammonemia and prevention of lipolysis (the breakdown of fat stored in fat cells) in the newborn may be lifesaving. Infants and young children with carnitineacylcarnitine translocase deficiency need to eat frequently to prevent a metabolic crisis. In general, it is often suggested that infants be fed every four to six hours, although some babies need to eat even more frequently than this. It is important that infants be fed during the night. They may need to be woken up to eat if they do not wake up on their own. Sometimes a lowfat, high carbohydrate diet is advised. Carbohydrates give the body many types of sugar that can be used as energy. In fact, for children needing this treatment, most food in the diet should be carbohydrates (bread, pasta, fruit, vegetables, etc.) and protein (lean meat and lowfat dairy food). Some children may be helped by taking Lcarnitine. This is a safe and natural substance that helps body cells make energy. It also helps the body get rid of harmful wastes. However, supplementation with carnitine remains controversial, as its efficacy remains unknown. Medium Chain Triglyceride oil (MCT oil) is sometimes used as part of the food plan for people with carnitineacylcarnitine translocase deficiency. This special oil has medium chain fatty acids that people with carnitineacylcarnitine translocase deficiency can use in small amounts for energy. You may be instructed to call your child's doctor at the start of any illness. Children with carnitineacylcarnitine translocase deficiency need to eat extra starchy food and drink more fluids during any illness (even if they may not feel hungry) or they could develop a metabolic crisis. |
What is (are) Chronic inflammatory demyelinating polyneuropathy ? | Chronic inflammatory demyelinating polyneuropathy (CIDP) is a neurological disorder that causes progressive weakness and impaired sensory function in the legs and arms. Symptoms often include tingling or numbness (first in the toes and fingers); weakness of the arms and legs; loss of deep tendon reflexes; fatigue; and abnormal sensations. CIDP is thought to be caused by an abnormal immune response in which the immune system mistakenly attacks and damages the myelin sheath (the covering that protects nerve fibers) of the peripheral nerves. CIDP is closely related to GuillainBarre syndrome (GBS) and is considered the "chronic counterpart" of GBS. Treatment may include corticosteroids, immunosuppressant drugs, plasma exchange, physiotherapy, and/or intravenous immunoglobulin (IVIG) therapy. |
What are the symptoms of Chronic inflammatory demyelinating polyneuropathy ? | What are the signs and symptoms of Chronic inflammatory demyelinating polyneuropathy? The Human Phenotype Ontology provides the following list of signs and symptoms for Chronic inflammatory demyelinating polyneuropathy. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Acute demyelinating polyneuropathy The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
What causes Chronic inflammatory demyelinating polyneuropathy ? | What causes chronic inflammatory demyelinating polyneuropathy (CIDP)? The exact underlying cause of CIDP is unknown, but there is evidence to support that it is related to the immune system and may have multiple triggers. It is thought to be caused by an abnormal immune response in which the immune system mistakenly attacks and damages the myelin sheath (the covering that protects nerve fibers) of the peripheral nerves. However, no specific provoking antigens or other predisposing factors for CIDP have been identified. In several case reports, treatment with tumor necrosis factoralpha inhibitors has been associated with the subsequent development of chronic demyelinating neuropathies. |
Is Chronic inflammatory demyelinating polyneuropathy inherited ? | Is chronic inflammatory demyelinating polyneuropathy (CIDP) inherited? CIDP is not known to be inherited and is considered an acquired disorder. No clear genetic predisposition or other predisposing factors for CIDP have been identified. |
What are the treatments for Chronic inflammatory demyelinating polyneuropathy ? | How might chronic inflammatory demyelinating polyneuropathy (CIDP) be treated? The standard therapies for CIDP appear to be equally effective and include: intravenous immune globulin (IVIG) adds large numbers of antibodies to the blood plasma to reduce the effect of the antibodies that are causing the problem glucocorticoids help reduce inflammation and relieve symptoms plasma exchange remove antibodies from the blood The treatment choice is influenced by the preference of the affected person, side effects, treatment cost, duration, ease of administration, and availability. Advantages and disadvantages of standard therapies may include the following: IVIG and plasma exchange may lead to a more rapid improvement in CIDP than glucocorticoid therapy, but are less likely than glucocorticoids to produce a remission IVIG is expensive, and its supply is sometimes limited Glucocorticoids are inexpensive, but chronic use is limited by common and important side effects Plasma exchange is expensive, invasive, and available only at specialized centers Other medications that suppress the immune system (immunosuppressants) may also be used. Physiotherapy may improve muscle strength, function and mobility. |
What is (are) Combined oxidative phosphorylation deficiency 16 ? | Combined oxidative phosphorylation deficiency 16, also know as infantile hypertrophic cardiomyopathy, is characterized by decreased levels of mitochondrial complexes. The symptoms and signs described include an enlarged heart muscle (hypertrophic cardiomyopathy) and fatty liver (hepatic steatosis), as well as eye problems, headache, paralysis of one side of the body, Leighlike lesions on brain magnetic resonance imaging (MRI), kidney insufficiency and neurological disease. It is caused by mutations in the MRPL44 gene, which results in mitochondrial dysfunction. The cases described seem to be inherited in an autosomal recessive pattern. Treatment is supportive. |

Signs and Symptoms Approximate number of patients (when available) Autosomal recessive inheritance Elevated hepatic transaminases Hypertrophic cardiomyopathy Increased serum lactate Infantile onset Microvesicular hepatic steatosis Variable expressivity The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
What is (are) Castleman disease ? | Castleman disease (CD) is a rare condition that affects the lymph nodes and related tissues. There are two main forms: unicentric CD and multicentric CD. Unicentric CD is a "localized" condition that is generally confined to a single set of lymph nodes, while multicentric CD is a "systemic" disease that affects multiple sets of lymph nodes and other tissues throughout the body. The exact underlying cause of CD is currently unknown; however, it is thought to occur sporadically in people with no family history of the condition. Treatment varies based on the form of the condition, the severity of symptoms and whether or not the affected person also has an HIV and/or human herpes virus type 8 (HHV8) infection. For more specific information about each form of CD, please visit GARD's unicentric Castleman disease and multicentric Castleman disease pages. |
What causes Castleman disease ? | What causes Castleman disease? The exact underlying cause of Castleman disease (CD) is poorly understood. However, some scientists suspect that an increased production of interleukin6 (IL6) by the immune system may contribute to the development of CD. IL6 is a substance normally produced by cells within the lymph nodes that helps coordinate the immune response to infection. Increased production of IL6 may result in an overgrowth of lymphatic cells, leading to many of the signs and symptoms of CD. It has also been found that a virus called human herpes virus type 8 (also known as HHV8, Kaposi's sarcomaassociated herpesvirus, or KSHV) is present in many people with multicentric CD, specifically. HHV8 is found in nearly all people who are HIVpositive and develop multicentric CD, and in up to 60% of affected people without HIV. The HHV8 virus may possibly cause multicentric CD by making its own IL6. |

What is (are) Erythema nodosum, idiopathic ? | Erythema nodosum (EN) is a skin condition in which red bumps (nodules) form on the shins. Less commonly, the nodules form on other areas of the body such as the thighs and forearms. The lesions begin as firm, hot, red, painful lumps and progress to a purplish color. EN is a type of inflammatory disorder affecting the layer of fat under the skin (panniculitis). Other symptoms that may accompany the skin findings include the following: fever, a general feeling of being ill. joint aches, and swelling of the affected area. In many cases, EN is presumed to be a delayed reaction to antigens associated with various infections, drugs, and certain systemic diseases. In many cases, however, EN has no identifiable cause (idiopathic); in these cases, clinical followup is needed to rule out certain conditions including inflammatory bowel disease, sarcoidosis, lymphoma, and Behcet's disease. Treatment may include rest, nonsteroidal antiinflammatory drugs (NSAIDS), steroids, hot or cold compresses, potassium iodide solution, and supportive bandages or compression stockings. Symptoms usually resolve within six weeks, but EN may become a chronic disorder lasting for months and, occasionally, for years. Approximately 30% cases of idiopathic EN may last more than 6 months. |
What is (are) Leber hereditary optic neuropathy ? | Leber hereditary optic neuropathy (LHON) is an inherited form of vision loss. Although this condition usually begins in a person's teens or twenties, rare cases may appear in early childhood or later in adulthood. For unknown reasons, males are affected much more often than females. This condition is caused by mutations in the MTND1, MTND4, MTND4L, and MTND6 genes. |
What are the symptoms of Leber hereditary optic neuropathy ? | What are the signs and symptoms of Leber hereditary optic neuropathy? Blurring and clouding of vision are usually the first symptoms of this disorder. These vision problems may begin in one eye or simultaneously in both eyes; if vision loss starts in one eye, the other eye is usually affected within several weeks or months. Over time, vision in both eyes worsens, often leading to severe loss of sharpness (visual acuity) and color vision. This condition mainly affects central vision, which is needed for detailed tasks such as reading, driving, and recognizing faces. In rare cases, other symptoms may occur such as heart arrhythmias and neurologic abnormalities (e.g., postural tremor, peripheral neuropathy, nonspecific myopathy, movement disorders), and a multiple sclerosislike disorder. However, a significant percentage of people with a mutation that causes Leber hereditary optic neuropathy do not develop any features of the disorder. Specifically, more than 50 percent of males with a mutation and more than 85 percent of females with a mutation never experience vision loss or related medical problems. Additional factors may determine whether a person develops the signs and symptoms of this disorder. Environmental factors such as smoking and alcohol use may be involved, although studies of these factors have produced conflicting results. Researchers are also investigating whether changes in additional genes, particularly genes on the X chromosome, contribute to the development of signs and symptoms. The Human Phenotype Ontology provides the following list of signs and symptoms for Leber hereditary optic neuropathy. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Leber hereditary optic neuropathy ? | What causes Leber hereditary optic neuropathy (LHON)? Leber hereditary optic neuropathy is a condition related to changes in mitochondrial DNA. Mutations in the MTND1, MTND4, MTND4L, and MTND6 genes cause LHON. These genes are contained in mitochondrial DNA. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA (known as mitochondrial DNA or mtDNA). The genes related to Leber hereditary optic neuropathy each provide instructions for making a protein involved in normal mitochondrial function. These proteins are part of a large enzyme complex in mitochondria that helps convert oxygen and simple sugars to energy. Mutations in any of the genes disrupt this process. It remains unclear how these genetic changes cause the death of cells in the optic nerve and lead to the specific features of Leber hereditary optic neuropathy. Click here to visit the Genetic Home Reference Web site to learn more about how mutations in these genes cause Leber hereditary optic neuropathy. |
Is Leber hereditary optic neuropathy inherited ? | How is Leber hereditary optic neuropathy (LHON) inherited? Leber hereditary optic neuropathy is an inherited condition that has a mitochondrial pattern of inheritance. The gene mutations that cause this condition are found in the mitochondrial DNA. Mitochondria are inherited from a person's mother, and as a result, only females pass mitochondrial conditions on to their children. Men can be affected, but they cannot pass the condition on to their children. Often, people who develop the features of Leber hereditary optic neuropathy have no family history of the condition. Because a person may carry a mitochondrial DNA mutation without experiencing any signs or symptoms, it is hard to predict which members of a family who carry a mutation will eventually develop vision loss or other medical problems associated with Leber hereditary optic neuropathy. It is important to note that all females with a mitochondrial DNA mutation, even those who do not have any signs or symptoms, will pass the genetic change to their children. |

What is (are) Churg Strauss syndrome ? | Churg Strauss syndrome is a condition characterized by asthma, high levels of eosinophils (a type of white blood cell that helps fight infection), and inflammation of small to medium sized blood vessels (vasculitis). The inflamed vessels can affect various organ systems including the lungs, gastrointestinal tract, skin, heart and nervous system. The exact cause of Churg Strauss syndrome is unknown, but it is thought to be an autoimmune disorder. Treatment may involve the use of glucocorticoids and/or other immunosuppressive therapies. |
What are the symptoms of Churg Strauss syndrome ? | What are the signs and symptoms of Churg Strauss syndrome? The specific signs and symptoms of Churg Strauss syndrome (CSS) vary from person to person depending on the organ systems involved. The severity, duration and age of onset also vary. CSS is considered to have three distinct phases prodromal (allergic), eosinophilic and vasculitic which don't always occur sequentially. Some people do not develop all three phases. The prodromal (or allergic) phase is characterized by various allergic reactions. Affected people may develop asthma (including a cough, wheezing, and shortness of breath); hay fever (allergic rhinitis); and/or repeated episodes of sinusitis. This phase can last from months to many years. Most people develop asthmalike symptoms before any other symptoms. The eosinophilic phase is characterized by accumulation of eosinophils (a specific type of white blood cell) in various tissues of the body especially the lungs, gastrointestinal tract and skin. The vasculitic phase is characterized by widespread inflammation of various blood vessels (vasculitis). Chronic vasculitis can cause narrowing of blood vessels, which can block or slow blood flow to organs. Inflamed blood vessels can also become thin and fragile (potentially rupturing) or develop a bulge (aneurysm). People with CSS often develop nonspecific symptoms including fatigue, fever, weight loss, night sweats, abdominal pain, and/or joint and muscle pain. Neurological symptoms (such as pain, tingling or numbness) are common and depend on the specific nerves involved. About half of affected people develop skin abnormalities due to accumulation of eosinophils in skin tissue. Symptoms of skin involvement may include purplish skin lesions, a rash with hives, and/or small bumps, especially on the elbows. Gastrointestinal involvement may cause various symptoms also. Heart problems may include inflammation of heart tissues and in severe cases, heart failure. The kidneys can also become involved, eventually causing glomerulonephritis.

Affected individuals should cover their skin from sun exposure by using sunscreen and wearing protective clothing such as longsleeve shirts, long pants, and hats with wide brims. Glasses may be worn to reduce sensitivity to bright light or to improve vision. Additional therapies or surgery may be used to treat crossed eyes (strabismus) or rapid eye movements (nystagmus). |
What is (are) Erythropoietic protoporphyria ? | Erythropoietic protoporphyria is a type of porphyria. Porphyrias are caused by an abnormality in the heme production process. Heme is essential in enabling our blood cells to carry oxygen and in breaking down chemical compounds in the liver. Erythropoietic protoporphyria is caused by impaired activity of ferrocheletase (FECH), an important enzyme in heme production. This results in the buildup of protoporphyrin in the bone marrow, red blood cells, blood plasma, skin, and eventually liver. Build up of protoporphyrin can cause extreme sensitivity to sunlight, liver damage, abdominal pain, gallstones, and enlargement of the spleen. |

What causes Erythropoietic protoporphyria ? | What is the genetic basis of erythropoietic protoporphyria? Erythropoietic protoporphyria is caused by mutations in the FECH gene. |
Is Erythropoietic protoporphyria inherited ? | How is erythropoietic protoporphyria (EPP) inherited? EPP is inherited in an autosomal recessive manner. In most cases, affected individuals have one severe (lossoffunction) mutation that is inherited from one parent, and another weak (lowexpression) mutation that is inherited from the other parent. In a small number of cases, an affected individual has two lossoffunction mutations. When 2 carriers of an autosomal recessive condition have children, each child has a: 25% (1 in 4) chance to be affected 50% (1 in 2) chance to be an unaffected carrier like each parent 25% (1 in 4) chance to be unaffected and not be a carrier |

Is Usher syndrome, type 1C inherited ? | How is Usher syndrome inherited? Usher syndrome is inherited in an autosomal recessive manner. This means that a person must have a change (mutation) in both copies of the diseasecausing gene in each cell to have Usher syndrome. One mutated copy is typically inherited from each parent, who are each referred to as a carrier. Carriers of an autosomal recessive condition usually do not have any signs or symptoms. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to have the condition, a 50% (1 in 2) chance to be an unaffected carrier like each parent, and a 25% chance to not be a carrier and not be affected. |

What is (are) Urachal cancer ? | Urachal cancer is a rare type of bladder cancer, making up less than 1% of all bladder cancers. Only about 350 cases have been described in the medical literature to date. The urachus is a primitive structure which before birth connected the bellybutton and the bladder. This connection normally disappears before birth, but in some people remains. Urachal cancers are classified as such based on location at the dome or anterior wall of the bladder and discovery of remnants of the urachus. Most urachal cancers are adenocarcinomas (cancers that develop from gland cells). Others may be sarcomas (which develop from connective tissue such as leiomyosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma), small cell carcinomas, transitional cell cancer, and mixed neoplasias. Most individuals with urachal cancer present with hematuria (blood in urine). Other symptoms may include abdominal pain, a palpable abdominal mass, mucinuria, and bacteriuria. Patients who present with early disease confined to the urachus have a good prognosis when treated with partial cystectomy, umbilicotomy, and urachal resection. The prognosis for those with advanced disease is less promising. |
What are the treatments for Urachal cancer ? | How might urachal cancer be treated? Surgical resection in the form of partial (segmental) or radical cystoprostatectomy is the main form of treatment. However, similar results are seen with a conservative surgery that involves partial cystectomy with umbilicotomy and removal of the urachus. The role of chemotherapy and radiation therapy for the treatment of urachal cancer is unclear, although some studies show that chemotherapy can induce objective response in some cases. Chemotherapy regimens that may be used include: singleagent 5fluorouracil (5FU), 5FU and cisplatin, 5FU, lomustine and vincristine, taxol and cisplatin, platinum and etoposide, and MVAC (methotrexate, vinblastine, doxorubicin, cisplatin) alone or in conjunction with radiation therapy. |

What is (are) Juvenile ossifying fibroma ? | Juvenile ossifying fibroma (JOF) is rare, benign tumor of the craniofacial (skull and face) bones. It is considered a "fibroosseous neoplasm" because it is characterized by an overgrowth of bone. Affected people generally experience a gradual or rapid, painless expansion of the affected bone or region. Other symptoms such as exophthalmos or nasal blockage can rarely be associated with the tumor depending on its exact location. In some cases, the condition can be particularly aggressive with rapid growth and significant facial disfigurement. Although the condition can affect people of all ages, it is most commonly diagnosed between the ages of 5 and 15. The exact underlying cause is currently unknown; however, most cases occur sporadically in people with no family history of the condition. JOF is usually treated with surgery. Because the recurrence rate of JOF ranges from 30% to 58%, continued followup is essential. |

What is (are) Juvenile retinoschisis ? | Juvenile retinoschisis is an eye condition characterized by impaired vision that begins in childhood and occurs almost exclusively in males. The condition affects the retina, which is a specialized lightsensitive tissue that lines the back of the eye. This affects the sharpness of vision. Central vision is more commonly affected. Vision often deteriorates early in life, but then usually becomes stable until late adulthood. A second decline in vision typically occurs in a man's fifties or sixties. Sometimes severe complications occur, including separation of the retinal layers (retinal detachment) or leakage of blood vessels in the retina (vitreous hemorrhage). These can lead to blindness. Juvenile retinoschisis is caused by mutations in the RS1 gene. It is inherited in an Xlinked recessive pattern. Lowvision aids can be helpful. Surgery may be needed for some complications. |

What causes Juvenile retinoschisis ? | What causes juvenile retinoschisis? Mutations in the RS1 gene cause most cases of juvenile retinoschisis. The RS1 gene provides instructions for producing a protein called retinoschisin, which is found in the retina. Studies suggest that retinoschisin plays a role in the development and maintenance of the retina, perhaps playing a role in cell adhesion (the attachment of cells together). RS1 gene mutations lead to a reduced amount or complete absence of retinoschisin, which can cause tiny splits (schisis) or tears to form in the retina. This damage often forms a "spokewheel" pattern in the macula, which can be seen during an eye examination. In about half of individuals, these abnormalities are seen in the area of the macula, affecting visual acuity. In the other half, the sides of the retina are affected, resulting in impaired peripheral vision. Some individuals with juvenile retinoschisis do not have a mutation in the RS1 gene. In these individuals, the cause of the disorder is unknown. |
Is Juvenile retinoschisis inherited ? | How is juvenile retinoschisis inherited? Juvenile retinoschisis is inherited in an xlinked recessive pattern. The gene associated with this condition is located on the X chromosome, one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation must be present in both copies of the gene to cause the disorder. Males are affected by Xlinked recessive disorders much more frequently than females. A striking characteristic of Xlinked inheritance is that fathers cannot pass Xlinked traits to their sons. In Xlinked recessive inheritance, a female with one mutated copy of the gene (mutation) in each cell is called a carrier. She can pass on the mutation, but usually does not experience signs and symptoms of the condition. Carrier women have a 50% chance of passing the mutation to their children, males who inherit the mutation will be affected; females who inherit the mutation will be carriers and will nearly always have normal vision. Carrier testing for atrisk female relatives and prenatal testing for pregnancies at increased risk are possible if the diseasecausing mutation in the family is known. |
