Ambry Genetics | RCV002411081 | SCV002715425 | likely pathogenic | Cardiovascular phenotype | 2017-05-24 | criteria provided, single submitter | clinical testing | The p.C352S variant (also known as c.1054T>A), located in coding exon 7 of the LDLR gene, results from a T to A substitution at nucleotide position 1054. The cysteine at codon 352 is replaced by serine, an amino acid with dissimilar properties. This alteration has been detected in several familial hypercholesterolemia (FH) cohorts and segregates with disease in one small FH family (Chiou KR et al. Atherosclerosis. 2011;216:383-9; Saban-Ruiz J et al. Atherosclerosis. 2015;241:e115; Hu M et al. J. Atheroscler. Thromb. 2016;23:520-31; Medeiros AM et al. Genet. Med. 2016;18:316-24). A number of alterations in the same codon (p.C352Y, p.C352W, p.C352R, and p.C352F) have also been associated with FH (Hobbs HH et al. Hum. Mutat. 1992;1:445-66; Bertolini S et al. Arterioscler Thromb Vasc Biol. 1999;19(2)408-18; Widhalm K et al. J Inherit Metab Dis. 2007;30(2):239-47; Marduel M et al. Hum. Mutat. 2010;31(11):E1811-24). 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. |
