Familial Hypercholesterolemia VCEP

The NM_000527.5(LDLR):c.2T>C (p.Met1Thr) variant is classified as Likely Pathogenic for Familial Hypercholesterolemia by applying evidence codes PM2, PVS1_Moderate, and PM5 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 - variant is absent from gnomAD (v2.1.1). PVS1_Moderate – variant is predicted to affect the initiation codon. PM5 - four other missense variants at this same codon have been reported, and one is Pathogenic: 1) NM_000527.5(LDLR):c.1A>C (p.Met1Leu) – Pathogenic by these guidelines. 2) NM_000527.5(LDLR):c.1A>G (p.Met1Val) - Likely pathogenic by these guidelines. 3) NM_000527.4(LDLR):c.3G>A (p.Met1Ile) - Likely pathogenic by these guidelines. 4) NM_000527.5(LDLR):c.3G>T (p.Met1Ile) - Likely pathogenic by these guidelines.

PVS1_Moderate

Variant is predicted to affect the initiation codon.

PM5

Four other missense variants at this same codon have been reported, and one is Pathogenic: 1) NM_000527.5(LDLR):c.1A>C (p.Met1Leu) – Pathogenic by these guidelines. 2) NM_000527.5(LDLR):c.1A>G (p.Met1Val) - Likely pathogenic by these guidelines. 3) NM_000527.4(LDLR):c.3G>A (p.Met1Ile) - Likely pathogenic by these guidelines. 4) NM_000527.5(LDLR):c.3G>T (p.Met1Ile) - Likely pathogenic by these guidelines.

PM2

Variant is absent from gnomAD (v2.1.1).
