We aimed to investigate the association between T2DM and the single nucleotide polymorphisms (SNPs) in genes (CDKAL1 and HHEX) associated with insulin secretion.Subjects and Methods: T2DM (n=1,169) and nondiabetic (NDM) (n=1,277) subjects were enrolled and the eight SNPs in CDKAL1 and HHEX genes associated with insulin secretion were genotyped in a Chinese population using MassARRAY. Then, the association of these SNPs with T2DM was analyzed.Results: Our results revealed that four SNPs (rs4712524, rs10946398, rs7754840 in CDKAL1, and rs5015480 in HHEX) showed significantly different distributions between the T2DM and NDM groups (P< 0.00625). The G allele of rs4712524 (P=0.004, OR=1.184; 95% CI=1.057– 1.327), C allele of rs10946398 (P< 0.001, OR=1.247; 95% CI=1.112– 1.398), and C allele of rs775480 in CDKAL1 (P< 0.001, OR=1.229; 95% CI=1.096– 1.387) functioned as risk alleles of T2DM. The C allele of rs5015480 in HHEX (P< 0.001, OR=1.295; 95% CI=1.124– 1.493) was also the risk factor for T2DM. The haplotype analysis revealed that CDKAL1 haplotype rs4712524G-rs10946398C-rs7754840C-rs9460546G (P=0.001, OR=1.210; 95% CI=1.076– 1.360) and HHEX haplotype rs1111875C-rs5015480C (P< 0.001, OR=1.364; 95% CI=1.180– 1.576) were the risk factors of T2DM.Conclusion: Our results revealed that genetic variations in CDKAL1 and HHEX were associated with T2DM susceptibility in Chinese population.Keywords: association study, single nucleotide polymorphisms, CDKAL1, HHEX, type 2 diabetes, Chinese population |
