not specified Benign:4
p.Ala1004Ser in exon 23 of MYH6: This variant is not expected to have clinical s ignificance because it has been identified in 0.3% (31/11578) of Latino chromoso mes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; d bSNP rs143978652). -
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. -

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affected with Cardiomyopathy (Carniel_2005, Brion_2009, Brion_2012, Hershberger_2010, Posch_2011, Waldmuller_2010-unpublished poster, Merlo_2013).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A, p.R663H), providing supporting evidence for a benign role (Waldmuller_2010, unpublished poster abstract).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. -

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. -
