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 links:

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]
