RCV000237741 | SCV004022382 | likely pathogenic | Hypercholesterolemia, familial, 1 | 2023-03-20 | reviewed by expert panel | curation | The NM_000527.5 (LDLR):c.2473A>G (p.Asn825Asp) variant is classified as Likely Pathogenic for Familial Hypercholesterolemia by applying evidence codes (PM2, PP3, PP4, PS4_Supporting, 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: This variant is absent from gnomAD (gnomAD v2.1.1). PP3: REVEL = 0.93. PP4: Variant meets PM2 and is identified in >1 index cases who fulfil FH diagnostic criteria after alternative causes of high cholesterol were excluded. PS4_Supporting: Variant meets PM2 and is identified in 2 unrelated index cases who fulfil FH diagnostic criteria. One index case fulfil criteria of TC > 8mmol/l and strong family history of CAD, Laurie et al, 2004, Canterbury Health Laboratories, New Zealand, PMID: 15556094. One index case with DLCN score >=6, Meshkov et al, 2021, National Medical Research Center for Therapy and Preventive Medicine, Russia, PMID: 33418990. PM5: Two other missense variants in the same codon: NM_000527.5 (LDLR):c.2475C>G (p.Asn825Lys), (ClinVarID 161265), is classified as Likely Pathogenic; NM_000527.5 (LDLR):c.2475C>A (p.Asn825Lys), (ClinVarID 252341), is classified as Pathogenic by these guidelines, therefore PM5 is met. |
