The rs1014290 Polymorphism of the SLC2A9 Gene Is Associated with Type 2 Diabetes Mellitus in Han Chinese

Aims. The SLC2A9 gene encodes the glucose transporter 9, with the abilities of transporting both glucose and uric acid and is involved in the pancreatic glucose-stimulated insulin secretion. The single nucleotide polymorphisms (SNPs) of SLC2A9 accounted for 5% variance of serum uric acid (UA). UA was identified as a risk factor for type 2 diabetes mellitus (DM). We investigated whether the SLC2A9 gene variations are associated with type 2 DM in Han Chinese. Methods. Three common SNPs of the SLC2A9, rs1014290, rs2280205, and rs3733591, were genotyped in 1003 Han Chinese randomly selected from Kaohsiung, Taiwan. Results. The variant SNP rs1014290 is associated with decreased 0.12-fold risk of type 2 DM (P=.002). Per-copy increase in the minor C-allele results in 0.13 mmol/L (P=.037) and 10.03 μmol/L (P=.016) decrease in serum glucose and UA, respectively. Conclusions. The SNP rs1014290 within the SLC2A9 gene is associated with type 2 DM in Han Chinese.
