Objective:To detect the distribution of the (C-106T) single nucleotide polymorphism and genotype of promoter region of aldose reductase gene and to study its relation to the susceptibility of microangiopathy in type 2 diabetes mellitus in Chinese Han from Chongqing.Methods:The aldose reductase gene in promoter region was amplified by polymerase chain reaction and the frequency of genotype of type 2 diabetes were analyzed by restriction enzyme BfaI.Results:The frequencies of genotype CC were significantly higher and the frequencies of genotype TT were much lower in type 2 diabetes patients with microangiopathy than in those without microangiopathy (χ 2=6.78 and 4.45
respectively
P<0.01 and P<0.05).Conclusion:This finding suggests that (C-106T) single nucleotide polymorphism in the aldose reductase gene promoter region may be associated with diabetic microangiopathy of Chinese Han type 2 diabetes.It may be a functional polymorphism and can serve as one of inherited marker for susceptibility of diabetic microangiopathy.
