Criteria Specifications for this VCEP
Evidence submitted by expert panel
Familial Hypercholesterolemia VCEP
The NM_000527.4(LDLR):c.1774G>A (p.Gly592Arg) variant is classified as Likely pathogenic for Familial Hypercholesterolemia by applying evidence codes PM2, PM5, PP3, PS4_Supportign and PP4 as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1016/j.gim.2021.09.012). The supporting evidence is as follows: PM2 - PopMax MAF = 0.00009799 (0.0098%) in South Asian exomes (gnomAD v2.1.1). It is below 0.02%, so PM2 is met. PM5 - 1 other missense variant in the same codon, NM_000527.5(LDLR):c.1775G>A (p.Gly592Glu) - classified as Pathogenic by the FH VCEP, so PM5 is met. PP3 - REVEL = 0.951. It is above 0.75, so PP3 is met. PS4_supporting - variant meets PM2 and was identified in 3 index cases with Dutch Lipid Clinic Scoring : Definite FH from U4M - Lille University & CHRU Lille, Université de Lille - CHRU de Lille (Accession: SCV000583882.1 in ClinVar), so PS4_Supporting is met. PP4 - variant meets PM2 and was identified in 3 index cases with clinical FH criteria (please see PS4 for details), so PP4 is met.
