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 sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 613 of the LDLR protein (p.Val613Ile). This variant is present in population databases (rs148181903, gnomAD 0.007%). This missense change has been observed in individuals with hypercholesterolemia (PMID: 16250003, 19837725). ClinVar contains an entry for this variant (Variation ID: 161288). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt LDLR protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Variant summary: LDLR c.1837G>A (p.Val613Ile) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.8e-05 in 251438 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1837G>A has been reported in the literature in individuals affected with Familial Hypercholesterolemia without strong evidence of causality (e.g. Fouchier_2005, Leigh_2008, Whittall_2010, Reijman_2023). These reports do not provide unequivocal conclusions about association of the variant with Familial Hypercholesterolemia. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 18325082, 16250003, 19837725, 36752612). ClinVar contains an entry for this variant (Variation ID: 161288). Based on the evidence outlined above, the variant was classified as uncertain significance. -
