RCV000035980 | SCV000564462 | uncertain significance | Primary dilated cardiomyopathy | 2021-10-13 | reviewed by expert panel | curation | The c.5726G>C (p.Arg1909Pro) variant in MYH7 has been reported as a de novo occurrence in 1 individual with dilated cardiomyopathy and myopathy features (PM6; Partners LMM ClinVar SCV000059632.5). Additionally, this variant reportedly segregated with DCM and in 2 affected relatives (Partners LMM ClinVar SCV000059632.5); however this data is currently insufficient to establish co-segregation and apply PP1. This variant was absent from large population studies (PM2; https://gnomad.broadinstitute.org, v2.1.1). Computational prediction tools and conservation analysis suggest that this variant may impact the protein (PP3). This variant was previously classified as likely pathogenic for DCM by this expert panel (EP) based on clinical judgement; however, upon re-evaluation, the EP has deemed that uncertain significance was more appropriate based on the available evidence. In summary, this variant is classified as uncertain significance for dilated cardiomyopathy in an autosomal dominant manner. MYH7-specific ACMG/AMP criteria applied (Kelly 2018 PMID:29300372): PM6, PM2, PP3. |
