Objective To investigate the association between -45C→G mutation at promoter of human urate transporter 1 gene and primary hyperuricemia. Methods The allele frequency and genotypo distribution of -45 C→G mutation at promoter of human urate trans-porter 1 gene were determined by PCR-RFLP in 217 patients with primary hyperuricemia and 419 normal controls. Results The frequencies of the G allele and CG genotype at promoter of human urate transporter 1 gene in patients were significantly higher than that in normal controls (P = 0. 031, P = 0.031). The levels of serum uric acid (UA) and triglyceride (TG) in subjects of CG genotype were significantly higher than those in the objects of CC genotype(t=3.058, t=3.699, P=0.002, P<0.001). There were no significant difference in the levels of total cholesterol (TC), fasting plasma glucose (FPG), urea nitrogen (BUN), creatinine (Cr) between the two groups (P>0.05). Conclusion The -45 C→G mutation at promoter of human urate transporter 1 gene may be related to primary hyperuricemia.

Primary hyperuricemia and gout are multifactorial conditions with strong genetic components. recently genome-wide association studies (GWAS) have revealed that several genes are related to primary hyperuricemia and gout which offers a thought for the research into the etiology, disease risk prediction, and prevention and treatment of this disease.

The incidence of hyperuricemia and relevant diseases has been increasing recently since the living improvement and dietary changing. Both patients and doctors do not pay enough attention to this disease, due to the lack of obvious clinical presentations in early stage. This paper comments on the relationship between hyperuricemia and gout, gouty nephropathy, impaired glucose metabolism,and atherosclerotic diseases in order to arouse enough attention to this disease.
