title: Association between interleukin 17A gene polymorphisms and risk of coronary artery disease.
abstract: Coronary artery disease (CAD) represents a leading cause of morbidity and mortality worldwide, and genetic factors contribute to the development of this disease. We conducted a case-control study to assess the association between interleukin 17A (IL17A) rs2275913 and rs3748067 polymorphisms and development of CAD. A total of 372 CAD patients and 372 healthy controls were recruited in our investigation between January 2013 and December 2014. Genotyping of IL17A rs2275913 and rs3748067 was carried out using polymerase chain reaction combined with restriction fragment length polymorphism. Logistic regression analysis revealed that CC [odds ratio (OR) = 3.81, 95% confidence interval (CI) = 2.11-7.16] and TC+CC (OR = 1.54, 95%CI = 1.11-2.14) rs3748067 genotypes were associated with an increased risk of CAD compared to the TT variant. Individuals carrying the TC+CC genotype were more likely to have a higher risk of CAD if they were smokers, with an adjusted OR (and 95%CI) of 2.20 (1.31-3.71). In conclusion, we suggest that the CC and TC+CC genotypes of rs3748067 are connected with increased risk of CAD in comparison to the wide-type genotype, particularly in smokers.
