RCV000238218 | SCV004022419 | likely pathogenic | Hypercholesterolemia, familial, 1 | 2023-04-28 | reviewed by expert panel | curation | The NM_000527.5 (LDLR):c.937T>C (p.Cys313Arg) variant is classified as Likely Pathogenic for Familial Hypercholesterolemia by applying evidence codes (PM2, PP3, PM1, PP4, PS4_Supporting) 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). PP3: REVEL=0.978. PM1: Variant meets PM2 and is one of the cysteine residues listed involving disulfide bone formation. PP4: Variant meets PM2 and is identified in >1 index cases who fulfil criteria for FH after alternative causes of high cholesterol were excluded. PS4_Supporting: Variant meets PM2 and is identified in 2 unrelated index cases reported in PubMed: one case fulfil Simon Broome criteria for definite or possible FH in PMID 22881376, reported by Usifo et al, 2012, from British Heart Foundation Laboratories, University College London, UK; one case fulfil DLCN >=6 in PMID 19318025 reported by Alonso et al, 2009, from Lipid Clinic, Fundacion Jimenez Diaz, Spain. PS3 not met: Functional data is not available. PM5 not met: Three other missense variants at same codon: NM_000527.5 (LDLR):c.937T>G (p.Cys313Gly), ClinVarID 251538, is classified as Uncertain significance; NM_000527.5 (LDLR):c.939C>G (p.Cys313Trp), ClinVarID 251540, is classified as Likely Pathogenic; NM_000527.5 (LDLR):c.938G>A (p.Cys313Tyr), ClinVarID 226339, is classified as Likely Pathogenic by these guidelines, therefore PM5 is not met. |
