Ambry Genetics	RCV000618195	SCV000736625	likely benign	Cardiovascular phenotype	2018-02-05	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.

Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00048 in 277246 control chromosomes, predominantly at a frequency of 0.005 within the African subpopulation in the gnomAD database. The observed variant frequency within African control individuals in the gnomAD database is approximately 200 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. c.2890G>T has been reported in the literature in individuals affected with hypoplastic left heart syndrome (Tomita-Mitchell_2016). These report(s) do not provide unequivocal conclusions about association of the variant with Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as likely benign.
