Abstract

Pro-protein convertase subtilisin/kexin type 9 (PCSK9) has been implicated in the regulation of the plasma levels of LDL-cholesterol. The SNP rs11591147 variant in PCSK9 gene is associated with low levels of LDL and reduced risk of coronary artery disease (CAD) in various populations. We therefore, investigated the association and protective role of the SNP rs11591147 with CAD in 94 patients and 94 healthy participants as controls. rs11591147 T>G was genotyped in all subjects by TaqMan Probe Real Time PCR, although we could not observe neither positive or insignificant association between SNP genotypes with CAD incidence. Allele frequencies also remained insignificant after performing comparison analyses between cases and controls. LDL-cholesterol and total cholesterol levels were not associated with the genotypes. Our data indicated that CAD or the plasma level of LDL-cholesterol was not associated with the reduction of CAD incidence in Iranian population, even in a population with high frequency of lipid-connected CAD risk factors. Prospective investigations should include more cases to accurately analyze the effect of SNP rs11591147 in protecting patients from CAD.
