Correlation of vascular endothelial growth factor gene C2587A polymorphism to diabetic nephropathy in type 2 diabetes mellitus

Objective To investigate the correlation of vascular endothelial growth factor(VEGF)-C2587A gene polymorphism to diabetic nephropathy in type 2 diabetes mellitus.Methods VEGF genotype was determined by allele-specific PCR(ASPCR) in 80 healthy controls and 216 patients with type 2 diabetes mellitus including 105 cases without nephropahy and 111 cases with nephropathy.VEGF genotype and allele frequencies were compared among these groups.Results(1)individuals with CC genotype had higher serum VEGF level than those with CA and AA groups.(2)the genotype CC distribution and C allele frequency in diabetes nephropathy were significantly higher than those in cases without nephropathy group and in controls.(3)Compared with genotype CA and AA class,the morbidity of diabetic nephropathy in genotype CC class was significantly increased.Conclusions VEGF-C2587A polymorphism is associated with the development of type 2 diabetic nephropathy.C allele is probably a susceptible gene of type 2 diabetic nephropathy.
