"human": "Return all entity pairs with the rs-snp relations in the text:\nFunctionality of sequence variants in the genes coding for the low-density lipoprotein receptor and apolipoprotein B in individuals with inherited hypercholesterolemia. Patients with familial hypercholesterolemia (FH) have elevated LDL-C levels, usually above the 90th percentile (P90) for age and gender. However, large-scale genetic cascade screening for FH showed that 15% of the LDL-receptor (LDLR) or Apolipoprotein B (APOB) mutation carriers have LDL-C levels below P75. Nonpathogenicity of sequence changes may explain this phenomenon. To assess pathogenicity of a mutation we proposed three criteria: (1) mean LDL-C 4P75 in untreated mutation carriers; (2) higher mean LDL-C level in untreated carriers than in untreated noncarriers; and (3) higher percentage of medication users in carriers than in noncarriers at screening. We considered a mutation nonpathogenic when none of the three criteria were met. We applied these criteria to mutations that had been determined in more than 50 untreated adults. Segregation analysis was performed to confirm nonpathogenicity. Forty-six mutations had been tested in more than 50 untreated subjects, and three were nonpathogenic according to our criteria: one in LDLR (c.108C4A, exon 2) and two in APOB (c.13154T4C and c.13181T4C, both in exon 29). Segregation analysis also indicated nonpathogenicity. According to our criteria, three sequence variants were nonpathogenic. The criteria may help to identify nonpathogenic sequence changes in genetic cascade screening programs.",

"human": "Extract the snp-gene relations from the text:\nUMD-CFTR: a database dedicated to CF and CFTR-related disorders. With the increasing knowledge of cystic fibrosis (CF) and CFTR-related diseases (CFTR-RD), the number of sequence variations in the CFTR gene is constantly raising. CF and particularly CFTR-RD provide a particular challenge because of many unclassified variants and identical genotypes associated with different phenotypes. Using the Universal Mutation Database (UMD) software we have constructed UMD-CFTR (freely available at the URL: http://www.umd.be/CFTR/), the first comprehensive relational CFTR database that allows an in-depth analysis and annotation of all variations identified in individuals whose CFTR genes have been analyzed extensively. The system has been tested on the molecular data from 757 patients (540 CF and 217 CBAVD) including disease-causing, unclassified, and nonpathogenic alterations (301 different sequence variations) representing 3,973 entries. Tools are provided to assess the pathogenicity of mutations. UMD-CFTR also offers a number of query tools and graphical views providing instant access to the list of mutations, their frequencies, positions and predicted consequences, or correlations between genotypes, haplotypes, and phenotypes. UMD-CFTR offers a way to compile not only disease-causing genotypes but also haplotypes. It will help the CFTR scientific and medical communities to improve sequence variation interpretation, evaluate the putative influence of haplotypes on mutations, and correlate molecular data with phenotypes.",

"human": "Return all entity pairs with the gene-snp relations in the text:\nWAVe: web analysis of the variome. DNA sequence variation is the underlying basis of common human traits and rarer single-gene disorders. Understanding the variome, the variants in an individual's genome, is essential to enable the ultimate goals of personalized medicine. This critical research field has grown dramatically in recent years, mostly due to the spread and development of genotyping technologies. Despite these activities being promoted by the Human Genome Variation Society and projects such as the Human Variome Project or the European GEN2PHEN Project, variome data-integration systems are far from being widely used in the research community workflow. Most of ongoing research is focused on improving locus-specific databases. Although the quality and manual curation of LSDBs adds true value to this domain, they are often narrow, heterogeneous, and independent systems. This hampers data harmonization and interoperability between systems, stifling the aggregation of data from LSDBs and related data sources. A new platform entitled Web Analysis of the Variome, WAVe, is introduced. It offers direct and programmatic access to multiple locus-specific databases, with the integration of genetic variation datasets and enrichment with relevant information. WAVe's agile and innovative Web interface is accessible at http://bioinformatics.ua.pt/WAVe.",

"human": "Extract the rs-gene relations from the text:\nNovel C2orf71 mutations account for ∼1% of cases in a large French arRP cohort. Autosomal-recessive retinitis pigmentosa (arRP) is a genetically heterogeneous group of disorders to which a novel gene, C2orf71, was recently associated. The purpose of our study was to establish the prevalence and nature of C2orf71 mutations in a clinically well-characterized cohort of 345 sporadic and arRP French cases. Direct sequencing of C2orf71 was performed in 209 subjects for whom mutations had previously been excluded by microarray technology and direct sequencing of EYS. Putative pathogenicity of the identified variants was evaluated through co-segregation analysis, screening of more than 188 control chromosomes and prediction programs. We identified two patients compound heterozygous for mutations predicted to lead to a premature stop codon, 3 of which are novel. In addition, 3 patients carried a single variant of likely pathogenicity. Furthermore a large number of novel putative non-disease causing variants were identified, highlighting the extremely polymorphic nature of C2orf71. To our knowledge, our study provides the first large scale screening of C2orf71 in a French arRP cohort through direct sequencing and suggests that it would account for approximately 1% of arRP cases.",

By combining exome sequencing in conjunction with genetic mapping, we have identified the first mutation in large mitochondrial ribosomal protein MRPL3 in a family of four sibs with hypertrophic cardiomyopathy, psychomotor retardation, and multiple respiratory chain deficiency. Affected sibs were compound heterozygotes for a missense MRPL3 mutation (P317R) and a large-scale deletion, inherited from the mother and the father, respectively. These mutations were shown to alter ribosome assembly and cause a mitochondrial translation deficiency in cultured skin fibroblasts resulting in an abnormal assembly of several complexes of the respiratory chain. This observation gives support to the view that exome sequencing combined with genetic mapping is a powerful approach for the identification of new genes of mitochondrial disorders.",

Copy number variants (CNVs) extend our understanding of the genetic diversity in humans. However, the distribution and characteristics of CNVs in Asian populations remain largely unexplored, especially for rare CNVs that have emerged as important genetic factors for complex traits. In the present study, we performed an in-depth investigation of common and rare CNVs across 8,148 individuals from the three major Asian ethnic groups: Chinese (n = 1,945), Malays (n = 2,399), and Indians (n = 2,217) in Singapore, making this investigation the most comprehensive genome-wide survey of CNVs outside the European-ancestry populations to date. We detected about 16 CNVs per individual and the ratio of loss to gain events is ∼2:1. The majority of the CNVs are of low frequency (<10%), and 40% are rare (<1%). In each population, ∼20% of the CNVs are not previously catalogued in the Database of Genomic Variants (DGV). Contrary to findings from European studies, the common CNVs (>5%) in our populations are not well tagged by SNPs in Illumina 1M and 610K arrays, and most disease-associated common CNVs previously reported in Caucasians are rare in our populations. We also report noticeable population differentiation in the CNV landscape of these Asian populations, with the greatest diversity seen between the Indians and the Chinese.",

"human": "Return all gene, rs, snp entity pairs with the Equals, AssociatedTo relations in the text with the format (head entity, relation type, tail entity):\nDilated cardiomyopathy-associated BAG3 mutations impair Z-disc assembly and enhance sensitivity to apoptosis in cardiomyocytes. Dilated cardiomyopathy (DCM) is characterized by dilation of left ventricular cavity with systolic dysfunction. Clinical symptom of DCM is heart failure, often associated with cardiac sudden death. About 20-35% of DCM patients have apparent family histories and it has been revealed that mutations in genes for sarcomere proteins cause DCM. However, the disease-causing mutations can be found only in about 17% of Japanese patients with familial DCM. Bcl-2-associated athanogene 3 (BAG3) is a co-chaperone protein with antiapoptotic function, which localizes at Z-disc in the striated muscles. Recently, BAG3 gene mutations in DCM patients were reported, but the functional abnormalities caused by the mutations are not fully unraveled. In this study, we analyzed 72 Japanese familial DCM patients for mutations in BAG3 and found two mutations, p.Arg218Trp and p.Leu462Pro, in two cases of adult-onset DCM without skeletal myopathy, which were absent from 400 control subjects. Functional studies at the cellular level revealed that the DCM-associated BAG3 mutations impaired the Z-disc assembly and increased the sensitivities to stress-induced apoptosis. These observations suggested that BAG3 mutations present in 2.8% of Japanese familial DCM patients caused DCM possibly by interfering with Z-disc assembly and inducing apoptotic cell death under the metabolic stress.",

"human": "Input text: A novel mutation impairing the tertiary structure and stability of γC-crystallin (CRYGC) leads to cataract formation in humans and zebrafish lens. Congenital cataract is one of the leading causes of human blindness. In this study, we identified a novel, heterozygous c.385G<T mutation in CRYGC that resulted in the substitution of a highly conserved glycine by cysteine at codon 129 (p.Gly129Cys) in a three-generation Chinese family with autosomal dominant congenital nuclear cataract by sequencing candidate genes. Using zebrafish as a model, we demonstrated that γC-crystallin p.Gly129Cys mutant caused the vacuole and the incomplete denucleation of lens, recapitulating the cataract phenotype in human beings. Molecular modeling and spectroscopic studies indicated that the mutation impaired the tertiary structure of the protein by modifying the H-bonding network in the C-terminal domain. The mutation led to a dramatic decrease in the thermal stability of γC-crystallin, and a significant increase in the propensity of aggregation when subject to storage at high concentrations, heat, and UV- irradiation stresses. Taken together, these results indicate that a novel γC-crystallin p.Gly129Cys mutation impaired the tertiary structure of the protein and caused cataract formation, which provides a new insight into how the mutation may affect the γC-crystallin structure, stability, and function. Our study also highlighted zebrafish as a valuable model tool for studying congenital inherited cataract.\n Output the rs-gene relations in the text.",
