Association of glutathione S-transferases M1 and T1 gene polymorphisms with the risk of metabolic syndrome in an Iranian population.

ABSTRACT: BACKGROUND:Glutathione S-transferases (GSTs) are important factors in cell sensitivity to oxidative stress and susceptibility to cardiometabolic disorders. We aimed to investigate the GSTM1 and T1 gene polymorphisms, as well as their interactions in metabolic syndrome (MetS) patients and healthy individuals in an Iranian population. MATERIALS AND METHODS:The study sample comprised of 220 healthy individuals (mean age: 41.9 - 15.1 years) and 165 MetS patients (mean age: 49.7 - 11.5 years). The diagnostic criteria for MetS were defined following the criteria provided by the modified National Cholesterol Education Program Adult Treatment Panel III. Genotyping of GSTM1 and T1 genes were performed using polymerase chain reaction. RESULTS:Our analyses have shown that neither GSTM1 (odds ratio [OR] =0.89, 95% confidence interval [CI]: 0.59 - 1.33, P = 0.57) nor GSTT1 (OR = 1.26, 95% CI: 0.76 - 2.02, P = 0.38) null genotypes were associated with increased risk. Moreover, no significant differences were observed between various combinations of GST genotypes. CONCLUSION:Contrary to our primary hypothesis, what we found disaffirms any kind of association between GSTM1 and T1 polymorphisms and the risk of MetS. However, being the first polymorphism study of GSTs in MetS patients, further studies are required to confirm our results in other populations.
