Description

The c.5704G>C (p.Glu1902Gln) variant in MYH7 has been identified in 0.096% (FAF 95% CI; 27/19954) of East Asian chromosomes in gnomAD v2.1.1 (https://gnomad.broadinstitute.org), which is a high enough frequency to be classified as likely benign based on thresholds defined by the ClinGen Inherited Cardiomyopathy Expert Panel (BS1; Kelly 2018 PMID:29300372). Allowing a variant to reach a likely benign classification based on BS1 alone represents a revision of the original ACMG/AMP framework by ClinGen’s Sequence Variant Interpretation Working Group (Tavtigian 2018 PMID: 29300386). In summary, this variant meets criteria to be classified as likely benign for cardiomyopathy in an autosomal dominant manner. MYH7-specific ACMG/AMP criteria applied (Kelly 2018 PMID:29300372): BS1
