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]

The c.259T>G (p.Trp87Gly) variant in the LDLR gene has been reported in multiple individuals with familial hypercholesterolemia (PMID: 2318961, 8054972, 8645371, 9259195, 9104431). It is located in the functionally important second LDLR type A repeat. Functional studies have demonstrated a deleterious effect of the p.Trp87Gly variant on LDL binding (PMID: 2318961, 8645371, 10735631). The variant is observed in gnomAD at a low minor allele frequency (8/282882). Multiple algorithms predicted this change to be deleterious. Therefore, the c.259T>G (p.Trp87Gly) variant in the LDLR gene is classified as pathogenic. -

The c.259T>G (p.Trp87Gly) variant, also known as p.Trp66Gly in LDLR gene that encodes for low density lipoprotein receptor, has been identified in numerous individuals (>100) affected with familial hypercholesterolemia (FH) (PMID:9104431, 2318961, 9259195, 9272705). This variant has also been reported in homozygous status in several individuals (>20) affected with severe FH (PMID: 8098448, 2318961, 9272705). This variant is considered as a founder mutation in the French-Canadian (PMID: 9272705) and Swedish population (PMID: 33955087). Experimental studies using patient derived lymphoblasts from true homozygotes revealed reduced LDLR binding and uptake (PMID: 31578082). Transfection of the mutant, p.Trp87Gly, protein in receptor deficient CHOldlA7 cells also showed significant reduction in LDL binding and uptake (PMID:31578082). Computational prediction tools suggest that the p.Trp87Gly variant may have deleterious effect on the protein function (REVEL score: 0.892). This variant is rare (24/1613912 chromosomes; 0.001487%) in the general population database, gnomAD v4.1.0 and interpreted as pathogenic by several submitters in the ClinVar database including the ClinGen variant curation expert panel (ClinVar ID: 3685). Therefore, the c.259T>G (p.Trp87Gly) variant in LDLR gene is classified as pathogenic. -

Variant summary: LDLR c.259T>G (p.Trp87Gly) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.8e-05 in 251490 control chromosomes. c.259T>G has been reported in the literature in multiple individuals affected with Familial Hypercholesterolemia (e.g. Leitersdorf_1990, Moorjani_1993, Banerjee_2019). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function, indicating the cells expressing the variant have reduced LDL-binding and uptake (e.g. Banerjee_2019). 11 clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories cited the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

This missense variant replaces tryptophan with glycine at codon 87 in the second LDLR type A repeat of the ligand binding domain of the LDLR protein. This variant is also known as p.Trp66Gly in the mature protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function. Experimental functional studies have demonstrated that this variant causes reduced LDL binding, internalization and uptake (PMID: 8645371, 10735631, 31578082). This variant has been identified in over 500 individuals affected with familial hypercholesterolemia (PMID: 2318961, 8098448, 9104431, 9259195, 9272705, 9676383, 12553167, 15528480, 16542394, 23669246, 30512145, 31345425, 31578082, 33955087, 34037665, 37607748, 39407785). This variant is common in individuals of European descent and is considered a founder mutation in the French-Canadian population (PMID: 9272705) and Swedish population (PMID: 33955087). It has been shown that this variant segregates with disease in multiple affected individuals across multiple families (PMID: 37607748; ClinVar SCV001960956.1). Homozygous individuals have been shown to carry significantly higher LDL-C levels than heterozygous individuals (PMID: 8098448, 36727130). This variant has been identified in 8/282882 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Based on available evidence, this variant is classified as Pathogenic. -

This sequence change replaces tryptophan, which is neutral and slightly polar, with glycine, which is neutral and non-polar, at codon 87 of the LDLR protein (p.Trp87Gly). This variant is present in population databases (rs121908025, gnomAD 0.006%). This missense change has been observed in individual(s) with familial hypercholesterolemia (PMID: 2318961, 12553167, 16542394). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It is commonly reported in individuals of European ancestry (PMID: 2318961, 12553167, 16542394). Invitae Evidence Modeling of clinical and family history, age, sex, and reported ancestry of multiple individuals with this LDLR variant has been performed. This variant is expected to be pathogenic with a positive predictive value of at least 99%. This is a validated machine learning model that incorporates the clinical features of 363,995 individuals referred to our laboratory for LDLR testing. This variant is also known as p.W66G. ClinVar contains an entry for this variant (Variation ID: 3685). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt LDLR protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects LDLR function (PMID: 8098448). For these reasons, this variant has been classified as Pathogenic. -

The p.Trp87Gly variant in LDLR is a well-established pathogenic variant for familial hypercholesterolemia (Leitersdorf 1990, Jensen 1996, Vohl 1997, Tybjaerg-Hansen 2005, Futema 2013), and is a known founder mutation in the French Canadian population where it has been reported in >400 individuals with FH, including >15 homozygous individuals (Vohl 1997). It has also been identified in 5/66740 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs121908025); however, this frequency is low enough to be consistent with the frequency of FH in the general population. Additionally, in vitro functional studies provide some evidence that the p.Trp87Gly variant may impact protein function (Leitersdorf 1990). In summary, this variant meets our criteria to be classified as pathogenic for FH in an autosomal dominant manner based upon its identification in a large number of affected individuals and low frequency in controls. -

The p.W87G pathogenic mutation (also known as c.259T>G), located in coding exon 3 of the LDLR gene, results from a T to G substitution at nucleotide position 259. The tryptophan at codon 87 is replaced by glycine, an amino acid with highly dissimilar properties. This mutation, historically reported as W66G, has been identified in multiple individuals with familial hypercholesterolemia (FH) (Leitersdorf E et al. J. Clin. Invest., 1990 Apr;85:1014-23; Brusgaard K et al. Clin. Genet., 2006 Mar;69:277-83; Langsted A et al. Lancet Diabetes Endocrinol, 2016 Jul;4:577-87). This alteration has been reported in FH patients across ethnic groups and has been designated a founder mutation in the French Canadian and Danish populations (Vohl MC et al. Clin. Genet., 1997 Jul;52:1-6; Jensen HK et al. Atherosclerosis, 1999 Oct;146:337-44). In vitro functional studies have demonstrated that this mutation causes defects in cell surface binding of LDL (Leitersdorf E et al. J. Clin. Invest., 1990 Apr;85:1014-23; Raungaard B et al. Clin. Genet., 2000 Feb;57:110-5). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
