Biesecker Lab/Clinical Genomics Section,National Institutes of Health RCV000172522 SCV000051370 likely benign not provided 2013-06-24 criteria provided, single submitter research
GeneDx RCV000212104 SCV000235751 likely benign not specified 2016-10-03 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Illumina Clinical Services Laboratory,Illumina RCV000302861 SCV000360601 uncertain significance Dilated cardiomyopathy 1HH 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Illumina Clinical Services Laboratory,Illumina RCV000359990 SCV000360602 benign Myofibrillar myopathy, BAG3-related 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Stanford Center for Inherited Cardiovascular Disease, Stanford University RCV000212104 SCV000280053 uncertain significance not specified 2014-06-03 no assertion criteria provided clinical testing Note this variant was found in clinical genetic testing performed by one or more labs who may also submit to ClinVar. Thus any internal case data may overlap with the internal case data of other labs. The interpretation reviewed below is that of the Stanford Center for Inherited Cardiovascular Disease. Given the lack of case data and the presence in individuals in the general population, we consider this variant a variant of uncertain significance. The variant is novel. In silico analysis with PolyPhen-2 predicts the variant to be probably damaging and mutation taster predicts it to be disease causing. The Grantham score is 64. The alanine at codon 479 is conserved across species, as are neighboring amino acids. Per the GeneDx report, a nearby variant has been reported with disease in HGMD, p.Arg477His. In total the variant has been seen in 14 of 7392 individuals from publicly available population datasets. The highest frequency was in 1 of 88 African individuals in 1000 genomes. The variant was reported online in 13 of 2203 African-American individuals in the NHLBI Exome Sequencing Project dataset (as of May 29th, 2014). It was not observed in the 4300 Caucasians in that dataset. The phenotype of those individuals is not publicly available. The dataset is comprised of multiple cohorts, some of which were recruited from the general population, others were enriched for common cardiovascular disease. Note that other variants with strong evidence for pathogenicity have been seen in this dataset, though at a lower frequency than this (Pan et al 2012). The variant was observed in 1 of 1089 individuals in 1000 genomes. Specifically, it was seen in 1 of 88 Yoruban (African) individuals. The variant is listed in dbSNP (rs34656239), pointing to the ESP and 1000 genomes data.
