Introduction & Aim: Diabetic nephropathy is the common process that leads to end-stage kidney disease (ESRD). Several studies showed that TGF-β is a major anti-inflammatory cytokine involved in extracellular matrix deposition and thickening of basement membrane of glomeruli. This study is aimed to evaluate the association of TGF-β1 gene polymorphisms (869T/C) and (509C/T) with complicated and uncomplicated type 2 diabetes mellitus. Methods: In this study, 250 Saudi male patients were classified, 100 healthy men as control, 80 uncomplicated type 2 diabetes mellitus male patients and 70 type 2 diabetes mellitus male patients with nephropathy. Blood and urine samples were collected from all groups for measurement of plasma glucose, urea, cholesterol, triglyceride, HDL-C, urea, creatinine and TGF-β1. In addition, a genotyping of TGF-β1 was done. Results: Our results showed a statistical difference in TGF-β1 levels in all groups, also a positive correlation between hyperglycemia and HbA1c with TGF-β1 level was detected. According to genotypes, only 869T/C genotypes were involved in susceptibility to T2DM and diabetic nephropathy. Both TC and CC genotypes were higher in T2DM patients compared with control (P<0.05), while only CC was higher in diabetic nephropathic patients compared with uncomplicated T2DM (P<0.05). Conclusion: It can be concluded that increase TGF-β level could be involved in the process of T2DM development and its nephropathic complication. In addition, the TC and CC genotypes of TGF-β1 869T/C were more susceptible to T2DM, while only CC genotype to diabetic nephropathy.
