The aim of this study was to evaluate the potential use of the I148M/PNPLA3 (rs738409) gene polymorphism as a susceptibility marker for premature coronary artery disease (pCAD) and/or cardiovascular risk factors in Mexican type 2 diabetes mellitus patients (T2DM). The polymorphism was genotyped by 5â² exonuclease TaqMan assays in a group of 2572 subjects (1103 with pCAD and 1469 healthy controls) belonging to the Genetics of Atherosclerotic Disease (GEA) Mexican Study. Anthropometric and biochemical measurements were performed in all individuals. The association between the I148M/PNPLA3 (rs738409) gene polymorphism with pCAD and other metabolic and cardiovascular risk factors was evaluated using logistic regression analysis under different statistical approaches including dominant, recessive, heterozygous, additive, and co-dominant models. The polymorphism was not associated with pCAD in the whole group of participants, however, when patients and controls were divided into those with and without T2DM, under additive model, the polymorphism was associated with the presence of pCAD only in patients with T2DM (OR = 1.20, 95% CI: 1.01-1.42, Padd = 0.042). On the other hand, under several models adjusted for age, gender, body mass index and T2DM, the polymorphism was associated with increased risk of fatty liver and elevated levels of alanine transaminase (ALT) in the whole group of pCAD patients and controls. In the control group, the polymorphism was associated with insulin resistance and coronary artery calcification (CAC) score â¥Â 10 under several models. The results suggest that the I148M/PNPLA3 (rs738409) polymorphism is associated with the presence of pCAD in T2DM patients and with some cardiometabolic parameters. The association detected with CAC in the control group indicates that this polymorphism could be a marker for subclinical atherosclerosis.
