Evidence submitted by expert panel

Familial Hypercholesterolemia VCEP

The NM_000527.5(LDLR): c.2446A>C (p.Lys816Gln) variant is classified as Uncertain significance - insufficient evidence, for Familial Hypercholesterolemia by applying evidence code PM2 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: This variant is absent from gnomAD (gnomAD v2.1.1)
