Polymorphism of rs599839 in the PSRC1 gene is associated with coronary artery disease in an Iranian population.

Introduction: Coronary artery disease (CAD) is the leading health complication worldwide because of its high prevalence and mortality. The association between CAD susceptibility and the rs599839 (C/T) polymorphism in the human proline and serine-rich coiled-coil ( PSRC1 ) was reported in a genome-wide association study. To validate this association, we performed this case-control study to genotype the 1p13.3 (rs599839) locus in a sample of the Iranian population with CAD (stenosis≥70% in≥1 coronary artery).
Methods: We performed an association analysis with PCR and Sanger sequencing of rs599839 (C/T) polymorphism and CAD risk in 280 CAD patients and 287 healthy controls defined as a coronary calcium score of zero and no noncalcified plaques in coronary computed tomography angiography. SPSS, version 16.0, was applied for statistical analysis.
Results: The rs599839 (C/T) locus showed a significant association with CAD ( P value<0.001). TT and CT genotypes were associated with CAD ( P value<0.001). Furthermore, the dominant status (TT+CT vs. CC) was associated with an increased risk of CAD (OR, 9.14; 95% CI, 3.77 to 22.15; and P value<0.001).
Conclusion: The study findings indicate strong evidence for rs599839 (C/T) association with CAD risk.
