Sulfonylurea receptor 1 (SUR1) gene codes the SUR1 protein that plays a key role in glucose-induced insulin secretion. In this study, we have investigated the relationship between the polymorphism in exon 31 of the SUR1 gene and type 2 diabetes, and its association with obesity in Turkish diabetic patients.Materials and methods: 90 patients (45 males and 45 females, aged 43-70 years old) who were followed up in the diabetes outpatient clinic were enrolled in the study. Serum glucose, triglyceride, cholesterol and blood HbA1c levels were determined. The SNPs in exon 31 were examined by a polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP) method.Results: A significant increase in the frequency of the A allele was observed in type 2 diabetic patients compared with that of the control group (41% vs. 24%, p
