Abstract

Introduction: Diabetes mellitus is a chronic disease whose global expansion gives it the characteristics of a pandemic. Diabetes risk factors are well known. In this work we proposed to study the role of genetic polymorphism of the eNOS G894T gene in the development of diabetes on the one hand and of these degenerative complications other. Methods: We conducted a prospective case-control study in which we included 200 subjects divided into 100 patients with type 2 diabetes and 100 controls in apparent good health. For each patient and control we measured lipid parameters, CRP-us and sought the G894T polymorphism of eNOS gene by PCR-RFLP. Results: The analysis of our results shows a statistically significant elevated TG values (p < 10﹣3), Lp (a) (p < 10﹣3), and CRP-us (p < 10﹣3) in type 2 diabetes compared with controls. The mutated genotypes of GT eNOS gene was significantly more frequent in diabetic patients. In our series, we did not notice any significant difference in genotype or allele frequency between diabetics with and without degenerative complications. Conclusion: The G894T polymorphism of eNOS gene appears to be a risk factor of T2DM. His role in the development of degenerative complications remains proved.
