Abstract:
Objective To explore the relation between the Integrin alpha 2 (ITGA2)-807 C/T gene and diabetic nephropathy (DN) in Han nationality in northern part of Guangxi. Methods 206 patients with type-2 diabetes were selected from the hospital. According to the diagnosis of diabetic nephropathy (DN) standards, 206 patients with type-2 diabetes were divided into diabetes without diabetic nephropathy (T2DM) and DN group, and 90 healthy people were selected as normal control (NC) group. The plasma lipid and lipoprotein levels were measured by routine method.And the genotypes and allele frequencies distribution were assessed by Polymerase chain reaction-restriction fragment length Polymorphism (PCR-RFLP). Results compared with the control group,plasma total cholesterol(TC),triglyceride(TG) and low density lipoprotein-cholesterol (LDL-C) levels in DN group blood were significantly higher (P < 0.05). ITGA2 gene - 807 - c/T genotype distribution and allele frequency in DN group were statistically significant (P<0.05). CT+TT genotypes and T allele frequency in DN group were significantly higher than control group (P<0.05).The relative risk for DN in subjects carrying T allele was 1.72 times of that in the C allele carriers(OR = 1.72, 95% CI = 1.72 ~ 2.517). And compared with control group and the DN group, ITGA2 gene-807-c/T genotype distribution and allele frequency differences in T2DM group had no statistical significance (P > 0.05). Conclusions The polymorphism of ITGA2-807C/T gene is associated with the development of DN in Han nationality in northern part of Guangxi. The T allele may be a genetic susceptibility genes for DN, which may promote the level of TC high expression and increase the risk of DN.
