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]

This missense variant replaces valine with methionine at codon 369 of the LDLR protein. This variant is also known as p.Val348Met in the mature protein. Computational prediction tools indicate that this variant's impact on protein structure and function is inconclusive. A high-throughput functional study has shown that this variant does not disrupt LDL uptake (PMID: 25647241). This variant has been reported in one individual affected with familial hypercholesterolemia (PMID: 30592178). It has also been reported in one individual affected with early-onset myocardial infarction and in one healthy control (PMID: 25487149). This variant has been identified in 2/251362 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
