Abstract
Background: Diabetes is the most common endocrine disorder that affects many people every year. Diabetic nephropathy is main complication of diabetes type 2. Renoprotective effects of vitamin “D” in chronic kidney disease have been reported that including diabetic nephropathy. The purpose of this study is to investigate the association between polymorphism (rs731236 (Taq1)) at gene receptor vitamin D (VDR), and the risk of diabetic nephropathy in patients with type 2 diabetes.
Methods In this case-control study, 104 patients with type 2 diabetes and nephropathy, 100 patients with type 2 diabetes and no nephropathy, and 98 people without diabetes and nephropathy who referred to the Diabetes Clinic of Tehran University of Medical Sciences were included . Clinical data were obtained and biochemical parameters were measured. The DNA samples were extracted from blood samples by phenol chloroform method. TheTaqI polymorphism (rs731236) was studied by TaqMan specific genotypes.
Results: Urea, creatinine and urine albumin values were significantly higher and glomerular filtration rate was lower in nephropathy group. Although frequency of TT genotype and also T allele was higher in nephropathy group, the difference was not significant.
Conclusion: There was no association between Taq1 polymorphism and diabetic nephropathy in the studied population
