Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000219999 SCV000270445 likely benign not specified 2015-05-06 criteria provided, single submitter clinical testing p.Asp377Asp in exon 12 of MYH6: This variant is not expected to have clinical si gnificance because it does not alter an amino acid residue and is not located wi thin the splice consensus sequence. It has been identified in 0.2% (18/10384) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broa dinstitute.org; dbSNP rs61742472).
Ambry Genetics RCV000247644 SCV000319800 likely benign Cardiovascular phenotype 2015-06-29 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: 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.
GeneDx RCV000219999 SCV000532856 likely benign not specified 2018-01-16 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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000219999 SCV001360439 benign not specified 2019-03-25 criteria provided, single submitter clinical testing Variant summary: MYH6 c.1131C>T alters a non-conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00023 in 276770 control chromosomes, predominantly at a frequency of 0.0017 within the African subpopulation in the gnomAD database. The observed variant frequency within African control individuals in the gnomAD database is approximately 68 fold of the estimated maximal expected allele frequency for a pathogenic variant in MYH6 causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African origin. To our knowledge, no occurrence of c.1131C>T in individuals affected with Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (X3 likely benign and X3 uncertain significance). Based on the evidence outlined above, the variant was classified as benign.
