Description

The p.E626K variant (also known as c.1876G>A), located in coding exon 13 of the LDLR gene, results from a G to A substitution at nucleotide position 1876. The glutamic acid at codon 626 is replaced by lysine, an amino acid with similar properties. This alteration has been reported in familial hypercholesterolemia (FH) cohorts; however, clinical details were limited (Fouchier SW et al. Hum Mutat, 2005 Dec;26:550-6; Medeiros AM et al. Atherosclerosis, 2010 Oct;212:553-8; Liu DJ et al. Nat Genet, 2014 Feb;46:200-4; Benito-Vicente A et al. Genet Med, 2015 Dec;17:980-8; Taylor JC et al. Nat Genet, 2015 Jul;47:717-726; Thormaehlen AS et al. PLoS Genet, 2015 Feb;11:e1004855; Grenkowitz T et al. Atherosclerosis, 2016 10;253:88-93; Besseling J et al. Eur Heart J, 2017 Feb;38:565-573; Benedek P et al. J Intern Med, 2018 12;284:674-684). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear.
