In the present study, we aimed to examine the role of two single-nucleotide polymorphisms (SNPs), rs3825807 and rs11556924, located in the ADAMTS7 and ZC3HC1 genes, respectively, associated with CAD in published GWASs in European populations and their possible contribution to the development of coronary atherosclerosis and cerebral LA atherosclerosis in a case-control study of an the Iranian population.
These findings extend the genetic association between rs11556924 and coronary artery disease risk by characterizing its effects on the encoded protein, NIPA.
The CAD-associated locus 7q32.2 is unusual in that the lead variant, rs11556924, is not in strong linkage disequilibrium with any other variant and introduces a coding change in ZC3HC1, which encodes NIPA.
A recent meta-analysis has described the ZC3HC1 rs11556924 polymorphism as one of the most important signals associated with coronary artery disease (CAD) in non-rheumatic Caucasian individuals.
