Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP4PS4_SupportingPS3_Moderate

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.2098G>A (p.Asp700Asn) variant is classified as Likely pathogenic for Familial Hypercholesterolemia by applying evidence codes PM2, PS3_Moderate, PS4_supporting and PP4 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 - PopMax MAF = 0.00006199 (0.006199%) in European (non-Finnish) exomes+genomes (gnomAD v2.1.1), so PM2 is Met.PS3_Moderate - Level 2 assays: PMID 34869944:Heterologous cells (CHO), FACS assays - result - 20% uptake.---- functional study is consistent with damaging effect, so PS3_Moderate is Met.PS4_supporting - Variant meets PM2 and is identified in 2 unrelated index cases: 1 index case with DLCN>=6 from Color Health, Inc, and 1 index case with Simon Broome criteria (TC of 9.8 mmol/L and personal or family history of CHD) from UK (PMID:23669246), so PS4_Supporting is Met.PP4 - Variant meets PM2 and is identified in 2 unrelated index cases (see PS4 for details), so PP4 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]
