Cardiomyopathy VCEP

The c.5326A>G (p.Ser1776Gly) variant in MYH7 has been reported in 12 individuals with hypertrophic cardiomyopathy (PMID:27532257; PMID:11861413; PMID:21239446; Partners LMM ClinVar SCV000203861.4; SHaRe consortium, PMID: 30297972) but has also been identified in 0.02% (2/8654) of East Asian chromosomes by ExAC (http://exac.broadinstitute.org). Since the MYH7 specifications state that PS4 is only applicable if the variant is absent or rare in large population studies, PS4 criterion was not applied (PMID:29300372). Computational prediction tools and conservation analysis suggest that this variant may impact the protein (PP3). In summary, this variant meets criteria to be classified as uncertain significance for hypertrophic cardiomyopathy in an autosomal dominant manner. MYH7-specific ACMG/AMP criteria applied (PMID:29300372): PP3
