Cardiomyopathy VCEP

The c.1988G>A (p.Arg663His) variant in MYH7 has been reported in >30 individuals with hypertrophic cardiomyopathy (PS4; PMID:27532257; PMID:10750581; PMID:11133230; PMID:12707239; PMID:15563892; PMID:16199542; PMID:15358028; AGCMC Sydney ClinVar SCV000212629.1; Invitae ClinVar SCV000219103.7; Partners LMM ClinVar SCV000059409.5; SHaRe consortium, PMID: 30297972). This variant segregated with disease in >15 affected individuals (PP1_Strong; PMID:10750581; Partners LMM ClinVar SCV000059409.5; SHaRe consortium, PMID: 30297972). This variant was identified in 2/66718 European chromosomes (PM2; http://exac.broadinstitute.org). This variant lies in the head region of the protein (aa 181-937) and missense variants in this region are statistically more likely to be disease-associated (PM1; PMID:27532257). In summary, this variant meets criteria to be classified as pathogenic for hypertrophic cardiomyopathy in an autosomal dominant manner.
