Description

The p.C358Y variant (also known as c.1073G>A), located in coding exon 8 of the LDLR gene, results from a G to A substitution at nucleotide position 1073. The cysteine at codon 358, located in the EGF-like 2 domain, is replaced by tyrosine, an amino acid with highly dissimilar properties. Pathogenic LDLR mutations that result in the substitution or generation of cysteine residues within the cysteine-rich LDLR class A repeats and EGF-like domains are common in familial hypercholesterolemia (FH) (Villéger L. Hum Mutat. 2002;20(2):81-7). This particular cysteine alteration has been detected in several individuals from familial hypercholesterolemia cohorts (Humphries SE et al. J Med Genet, 2006 Dec;43:943-9; Abifadel M et al. Hum Mutat, 2009 Jul;30:E682-91; Vladimirova-Kitova LG et al. Echocardiography, 2011 Feb;28:223-34). Internal structural analysis indicates this alteration eliminates a disulfide bond critical for the structural integrity of the EGF-like 2 domain (Ambry internal data). 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 majority of available evidence to date, this variant is likely to be pathogenic.
