title: G109T polymorphism of SLC22A12 gene is associated with serum uric acid level, but not with metabolic syndrome.
abstract: SLC22A12 gene, encoding urate transport 1, has been known to be responsible to urate metabolism. This study sought to determine the association between the novel G109T polymorphism in SLC22A12 with serum uric acid and the development of metabolic syndrome in Korean male subjects. A total of 132 healthy male subjects were enrolled in this study. Metabolic syndrome was determined using the modified guidelines for metabolic syndrome proposed by the National Cholesterol Education Program's Third Adult Treatment Panel. Genotyping for the SLC22A12 gene was assessed using denaturing high-performance liquid chromatography analysis. Serum uric acid and fractional excretion of uric acid (FEUA) from blood and urine samples were measured. Frequencies of the 109GG, 109GT, and 109TT genotypes were 57.6, 38.6, and 3.8%, respectively. Serum uric acid levels and FEUAs were significantly different among the three genotypes of the G109T polymorphism (P = 0.035 and P = 0.033, respectively). In addition, subjects of genotypes with the T allele had lower uric acid levels and higher FEUAs compared to those with the 109GG genotype (P = 0.007 and P = 0.031, respectively). The G109T polymorphism of the SLC22A12 gene has no association with metabolic syndrome. However, a number of metabolic syndrome components were related to serum uric acid level (r = 0.285, P = 0.001) and also significantly different between genotype with and without T allele (P = 0.008). The novel G109T polymorphism of the SLC22A12 gene is related to serum uric acid level, but not to the development of metabolic syndrome.
