Association of rs2781666 G/T polymorphism of arginase I gene with myocardial infarction in Tunisian male population

Abstract

Objectives: The aim of this study was to investigate the association between rs2781666 G/T polymorphism of arginase I (ARG I) gene and myocardial infarction (MI) in the Tunisian male population. Design and methods: Three hundred eighteen patients with MI and 282 controls were recruited. The rs2781666 G/T polymorphism of ARG I was determined by PCR-RFLP analysis. Results: Patients had significantly higher frequency of TT genotype compared to controls (10.4% vs. 6.7%; p < 0.001). The MI patients showed higher frequency of T allele compared to the controls [0.33 vs. 0.22; OR (95% CI), 1.79 (1.37-2.34), p < 0.001]. The association between rs2781666 G/T polymorphism of ARG I gene and MI remained significant after adjustment for other well-established risk factors. Conclusion: A significant association between rs2781666 G/T polymorphism of ARG I gene and MI was found in the Tunisian male population. © 2009.
