Abstract

Introduction. It has been shown that gene polymorphisms influence the development and progression of chronic kidney disease (CKD). Many studies have indicated that aldosterone synthase CYP11B2 gene polymorphism (-344C>T) influences the aldosterone level, urinary aldosterone excretion, blood pressure, and left ventricular size and mass. We aimed to investigate whether there is an effect of CYP11B2 -344 C>T polymorphism on the development of CKD in a Turkish population.

Material and Methods. A total of 240 patients with stage 5 CKD and 240 age- and sex-matched healthy individuals were included in the study. Genotyping of CYP11B2 gene -344 T>C promoter polymorphism was carried out using polymerase chain reaction and restriction fragment length polymorphism methods.

Results. No significant differences were found in the genotype distribution of CYP11B2 -344 C>T polymorphism between the patients and controls; however, -344 C>T polymorphism was significantly more frequent among the CKD patients with diabetes mellitus as compared to those with it (P = .02). Diabetic CKD patients with TC genotype had a 2-fold increased risk for development of the disease than the CKD patients without diabetes mellitus (odds ratio, 2.21; 95% confidence interval, 1.04 to 4.67).

Conclusions. Our study suggests that the CYP11B2 gene -344 C>T polymorphism may have an effect on the development of CKD in diabetic patients.
