    Abstract:
    Interleukin-23 (IL-23) has been associated with atherosclerosis in both humans and animal models with contradictory results. This cytokine is conformed by an α p19 (encoded by IL-23A gene) and a β p40 subunit (encoded by IL-12B gene). The aim of this study was to evaluate the association of two polymorphisms located within (rs11171806) or near (rs2066808) of the IL-23A gene with the presence of premature coronary artery disease (CAD) and with cardiometabolic parameters. The rs2066808 and rs11171806 polymorphisms were determined in 2249 Mexican individuals (1160 with premature CAD and 1089 healthy controls). Under recessive and codominant 2 models, adjusted by confounding variables, the rs2066808 polymorphism could increase the genetic risk of premature CAD (odds ratio [OR] = 4.567, 95% confidence interval [CI]: 1.03-20.24, Precessive = 0.046 and OR = 4.606, 95% CI: 1.039-20.43, Pcodominant2 = 0.044). The association of the polymorphisms with cardiovascular risk factors was evaluated separately in premature CAD patients and healthy controls. In patients, the rs2066808 polymorphism could decrease the genetic risk of hyperinsulinemia, insulin resistance, and hypoalphalipoproteinemia, and increase the genetic risk of hyperuricemia, whereas the rs11171806 polymorphism could decrease the genetic risk of hyperinsulinemia and insulin resistance. In healthy controls, the rs11171806 polymorphism could decrease the genetic risk of hyperinsulinemia. These findings suggest that the rs2066808 polymorphism located near the IL-23A gene could increase the genetic risk of premature CAD and both studied polymorphisms could be associated with some cardiometabolic parameters in premature CAD patients and in healthy controls.
