RESUMO
Objective To explore the relationship of KCNQ1 rs2237892 polymorphism with type 2 diabetes mellitus(T2DM) in Hefei. Methods A total of 104 healthy individual(control group) and 84 patients with T2DM(T2DM group) were enrolled. The rs2237892 polymorphism KCNQ1 gene was detected by PCR-RFLP. The genetype, allele frequency, related clinical and biochemical data were compared between the two groups. Results There were no significant differences in alleles or genotype frequencies of KCNQ1 rs2237892 gene among control group and T2DM group. The result of Logistic regression analysis showed that the risk of T2DM in the subjects with CT genetype of rs2237892 was 1. 44 times of those with CC genotype(OR =1.44, 95％ CI: 1. 06 ～ 1. 95, P=0. 02). Conclusion KCNQ1 rs2237892 gene may be the susceptibility gene of T2DM in Hefei.
