Popis: Background: Coronary artery disease (CAD) is major cause of death and morbidity worldwide. Arachidonate 12/15-lipoxygenase (ALOX) is a member of the lipid peroxidizing enzyme family and implicated in the pathogenesis of atherosclerosis, but with contradicting results. Aim: The present study aimed to investigate the association of two polymorphisms in ALOX15 (rs2619112 and rs7217186) and the risk of CAD in North Indian population. Methods: A total of 500 angiographically confirmed CAD patients and 500 control subjects of North Indian population were recruited in the case-control study and genotyped by PCR-RFLP. Results: The data showed a significant association between the two polymorphisms and CAD. Multiple logistic regression revealed heterozygous genotype of both the polymorphisms viz. GA of rs2619112 and CT of rs7217186 to be associated with significant high risk of CAD after adjustment for confounders (p = 0.034, OR = 2.274, 95% CI (1.062–4.870) and p = 0.000, OR = 3.407, 95% CI (2.092–5.548) respectively). Stratified analysis based on gender showed GA and AA of rs2619112 each significantly increased the risk of CAD in females (p = 0.001, OR = 13.120, CI = 2.780–61.928; p = 0.028, OR = 5.393, CI = 1.196–24.316 respectively) whereas only GA increased CAD risk in males (p = 0.005, OR = 2.277, CI = 1.290–4.020). In case of rs7217186, CT and TT showed a significant high risk of CAD in males (p = 0.000, OR = 4.048, CI = 2.678–6.119; p = 0.000, OR = 2.861, CI = 1.928–4.245). Conclusion: The present study shows that rs7217186:C > T and rs2619112:G > A of ALOX15 are associated with increased risk of CAD in the North Indian population.
