Criteria Specifications for this VCEP
Evidence submitted by expert panel
Familial Hypercholesterolemia VCEP
NM_000527.5(LDLR):c.1783C>T (p.Arg595Trp) variant is classified as Pathogenic for Familial Hypercholesterolemia by applying evidence codes (PS4, PP1_Strong, PM2, PP3 and PP4) as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1101/2021.03.17.21252755). The supporting evidence is as follows: PS4 - Variant meets PM2. Variant identified in 12 index cases. PP1_strong - 10 informative meioses identified by Laboratory of Genetics and Molecular Cardiology. PM2 - PopMax MAF = 0.00001548 (0.0015%) in European non-Finnish (gnomAD v2.1.1). PP3 - REVEL: 0,89. PP4 - Variant meets PM2. Variant identified in 12 index cases fulfilling validated clinical criteria for FH (6 cases with Simon-Broome or DLCN criteria from Ambry Genetics; 2 cases with Simon-Broome from Color laboratory; 3 cases with Simon-Broome criteria from Laboratory of Genetics and Molecular Cardiology; 1 case with Simon-Broome criteria from GeneDx).
