Frequency of KCNQ1 Variant rs2237892 in Type 2 Diabetes in East Azerbaijan Population, Northwest of Iran

Genome-wide association studies in Asian population for the first time identified common variants in the KCNQ1 gene to be associated with type 2 diabetes in Japanese populations, recently. This result has been replied in some other East Asian population but, still now, there is no any report about this subject in Iranian population. The aim of this study was to investigate the frequency of KCNQ1 variants in type 2 diabetes in East Azerbaijan population, northwest of Iran. A total of 75 T2D and 90 normal East Azerbaijan subjects were entered the study. A demographic date was recorded for all subjects. Genomic DNA was extracted from the whole blood, and the KCNQ1 single nucleotide polymorphisms (SNPs) rs2237892 were genotyped with PCR-RFLP technique. The results of the study indicated an increased level of FBS and HbA1C among T2D cases (P
