Type 2 diabetes (T2D) is a chronic disorder with different genetics and environmental factors. It is one of growing diseases in the world. Previous studies show association between Transcription Factor 7 Like2 (TCF7L2) and T2D. The current study set to evaluate the relation between TCF7L2 polymorphisms and T2D in Southeast Iran. The present case-control study was done on 250 T2D and 250 healthy controls (HCs). For genotyping polymorphisms TCF7L2 (rs11196205) and (rs4132670) Amplification-Refractory Mutation System-Polymers Chain Reaction (ARMS-PCR) was used. The results showed frequency rates of GC and CC genotypes increased in patients compared to controls (31% vs. 6% and 55% vs. 8%, respectively), showing a statistically significant difference (OR=2.67(1.37-5.21), P<0.05 and OR=3.31(1.92-5.71), P< 0.05, respectively). The C allele was associated with an increased risk of T2D, with the frequency of 28% and 11% in patients and controls, respectively (OR=3.11 (2.22-4.37), P< 0.05). Another Polymorphism of this gene TCF7L2 (rs4132670) was not associated with T2D.
