Relationship Between SLC22A1 and SLC22A4 Gene Polymorphisms and Risk of Type 2 Diabetes in Chinese Han Population.
This study was to investigate the relationship between SLC22A1 and SLC22A4 gene polymorphisms and genetic susceptibility to type 2 diabetes in Chinese Han population. The research group comprised 110 Chinese Han patients with type 2 diabetes, and the control group included 110 healthy volunteers. The polymorphisms of SLC22A1 gene rs628031 and rs2282143 loci and SLC22A4 gene rs2073838 and rs272893 loci were detected in the two groups. Statistically significant differences were identified in the genotype distributions of SLC22A1 gene rs628031 and rs2282143 loci between the two groups (p < 0.05). The A allele frequency of SLC22A1 gene rs628031 locus and the T allele frequency of rs2282143 locus were higher in the research group than in the control group (p < 0.05). The genotype distributions of rs272893 locus showed a significant difference between the two groups (p < 0.05), but not SLC22A4 gene rs2073838 locus (p > 0.05). The polymorphisms of SLC22A1 gene rs628031 and rs2282143 loci and SLC22A4 gene rs272893 locus of patients with type 2 diabetes indicated a significant difference between the two groups, suggesting that these genetic locus mutations increase the risk of type 2 diabetes in Chinese Han patients.
