Genes affected

MYH6 (HGNC:7576): (myosin heavy chain 6) Cardiac muscle myosin is a hexamer consisting of two heavy chain subunits, two light chain subunits, and two regulatory subunits. This gene encodes the alpha heavy chain subunit of cardiac myosin. The gene is located approximately 4kb downstream of the gene encoding the beta heavy chain subunit of cardiac myosin. Mutations in this gene cause familial hypertrophic cardiomyopathy and atrial septal defect 3. [provided by RefSeq, Feb 2017]

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. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: MYH6 c.3010G>T (p.Ala1004Ser) results in a conservative amino acid change located in the Myosin tail domain (IPR002928) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00093 in 251486 control chromosomes, predominantly at a frequency of 0.0021 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 84 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 Latino origin. c.3010G>T has been reported in the literature in sequencing studies among individuals affected with Cardiomyopathy (Carniel_2005, Brion_2009, Brion_2012, Hershberger_2010, Posch_2011, Waldmuller_2010-unpublished poster, Merlo_2013). These data indicate that the variant may be associated with disease. At-least one co-occurrence with other pathogenic variant(s) has been reported (MYH7 c.1988G>A, p.R663H), providing supporting evidence for a benign role (Waldmuller_2010, unpublished poster abstract). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Nine clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments. Based on the evidence outlined above, the variant was classified as likely benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -
