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]

Collection Method:clinical testing

This missense variant (also known as p.Ser566Arg in the mature protein) replaces serine with arginine at codon 587 of the LDLR protein. Computational prediction suggests that this variant may have a deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with familial hypercholesterolemia (PMID: 16250003, 33740630) and in an individual affected with coronary artery disease (PMID: 27050191). It has also been reported in a healthy control individual (PMID: 30586733). This variant has been identified in 4/251490 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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 expected to disrupt LDLR protein function. ClinVar contains an entry for this variant (Variation ID: 252021). This missense change has been observed in individual(s) with familial hypercholesterolemia (PMID: 16250003, 20506408, 33740630). This variant is present in population databases (rs753430282, gnomAD 0.004%). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 587 of the LDLR protein (p.Ser587Arg). -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In silico analysis suggests this variant may impact gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; This variant is associated with the following publications: (PMID: 16250003, 20506408, 27050191, 30586733, 27044878, 37409534, 33740630) -

The p.S587R variant (also known as c.1761C>G), located in coding exon 12 of the LDLR gene, results from a C to G substitution at nucleotide position 1761. The serine at codon 587 is replaced by arginine, an amino acid with dissimilar properties. This alteration was detected in a hypercholesterolemia, coronary artery cohorts; however, clinical details were limited (Fouchier SW et al. Hum. Mutat., 2005 Dec;26:550-6; Khera AV et al. J. Am. Coll. Cardiol., 2016 Jun;67:2578-89; Leren TP et al. Atherosclerosis, 2021 04;322:61-66). This alteration was also detected in a control subject in a whole exome sequencing cohort (Khera AV et al. Circulation, 2019 03;139:1593-1602). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
