Description

The variant was co-segregated with Cardiomyopathy, hypertrophic, 7 in multiple affected family members with additional meioses (PMID: 9241277, 15607392, 23283745, 24111713, 25132132, PP1_S). Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 11735257, PS3_S). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.8, 3CNET: 0.979, PP3_P). A missense variant is a common mechanism associated with Cardiomyopathy (PP2_P). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000016, PM2_M). The variant is located in a well-established functional domain or exonic hotspot, where pathogenic variants have frequently reported (PM1_M). Different missense changes at the same codon have been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000012419,VCV000012426, PM5_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.
