dbSNP rs746939188: LDLR:p.Trp533* (chr19-11116105-G-A) – ACMG Classification: Pathogenic (12 pts)

Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PM2PVS1PP4PS4_Supporting

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.1598G>A (p.Trp533Ter) variant is classified as Pathogenic for Familial Hypercholesterolemia by applying evidence codes PVS1, PM2, PP4 and 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: PVS1 - variant is nonsense upstream of amino acid 830, so PVS1 is met.PM2 - PopMax MAF = 0.000008792 (0.0009%) in European Non-Finnish exomes (gnomAD v2.1.1). It is below 0.02%, so PM2 is met.PP4 - variant meets PM2.identified in: - 1 index case who fulfills SB criteria from Cardiovascular Research Group, Instituto Nacional de Saude Doutor Ricardo Jorge.- 1 index case who fulfills SB criteria from Marduel et al. 2010 (PMID:20809525).so PP4 is met.PS4_supporting - variant meets PM2 and was identified in 2 unrelated index cases from different labs (please see PP4 for details), so PS4_Supporitng is met.

Genes affected

LDLR (HGNC:6547): (low density lipoprotein receptor) The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. The encoded protein is normally bound at the cell membrane, where it binds low density lipoprotein/cholesterol and is taken into the cell. Lysosomes release the cholesterol, which is made available for repression of microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, the rate-limiting step in cholesterol synthesis. At the same time, a reciprocal stimulation of cholesterol ester synthesis takes place. Mutations in this gene cause the autosomal dominant disorder, familial hypercholesterolemia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2022]
