Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP4

This summary comes from the ClinGen Evidence Repository: NM_000527.5(LDLR):c.4G>C (p.Gly2Arg)variant is classified as uncertain significance - insufficient evidence for Familial Hypercholesterolemia by applying evidence code PM2 and PP4 as defined by the ClinGen Familial NM_000527.5(LDLR):c.4G>C (p.Gly2Arg)variant is classified as uncertain significance - insufficient evidence for Familial Hypercholesterolemia by applying evidence code PM2 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 = 0.00016 (0.016%) in African exomes (gnomAD v2.1.1).PP4 - Variant meets PM2 and is identified in one index cases who fulfills SB criteria for FH (1 case from CGMC, UFGOD (APHP.Sorbonne Université, Hôpital de la Pitié-Salpêtrière)).

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]
LDLR-AS1 (HGNC:54407): (LDLR antisense RNA 1) This gene represents a regulatory lncRNA that overlaps the 5' UTR and coding sequence of the LDLR (low density lipoprotein receptor) gene. This lncRNA overlaps LDLR in the antisense orientation, and has been shown to downregulate production of the low density lipoprotein receptor. [provided by RefSeq, Jul 2019]
