Description

The p.D227E pathogenic mutation (also known as c.681C>G), located in coding exon 4 of the LDLR gene, results from a C to G substitution at nucleotide position 681. The aspartic acid at codon 227 is replaced by glutamic acid, an amino acid with highly similar properties. This founder mutation (also referred to as p.D206I accounts for the majority of familial hypercholesterolemia (FH) in the Afrikaner population (Leitersdorf et al. J Clin Invest.1989;84(3):954-61; King et al. N Z Med J. 2010;123(1319):79-82). This alteration has been reported in affected individuals of multiple ethnicities in both the heterozygous and homozygous states (e.g., Gudnason et al. Arterioscler. Thromb. 1993;13(1):56-63; Leren et al. Semin Vasc Med. 2004;4(1):75-85; Bertolini et al Atherosclerosis 2013;227(2):342-348; Sharifi et al. Metab. Clin. Exp. 2016;65(3):48-53). In an assay testing LDLR function, this variant showed a functionally abnormal result (Fourie A et al. Biochem J. 1988;255(2):411-5). 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.
