Variant summary
Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_ModerateBP6BS1BS2
The NM_004281.4(BAG3):c.1436C>T(p.Ala479Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000158 in 1,614,138 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

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. -

Dilated cardiomyopathy 1HH Uncertain:1
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. -
Myofibrillar myopathy 6 Benign:1
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. -
BAG3-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Cardiovascular phenotype Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
