Abstract:
ObjectiveTo investigate the association between a new identified Gly82Ser polymorphism of RAGE gene and diabetic microangiopathy,a case control study of 260 Chinese subjects (including 156 type 2 diabetics with or without nephropathy or retinopathy and 104 non diabetic control) was performed.MethodsGenotype frequencies of Gly82Ser polymorphism were studied by PCR RFLP analysis with AluI digestion.ResultsThe most frequent genotype and allele of Gly82Ser polymorphism of RAGE gene in Chinese were genotype GG and allele G.Their frequency distribution showed significant difference between Chinese and Caucasian.There was no difference in genotype frequencies or allele frequencies between type 2 diabetic patients (DN 0) and the control subjects.Genotype and allele frequencies did not differ in type 2 diabetic subjects with nephropathy or without nephropathy.Moreover,there were no associations between diabetic patients with or without retinopathy in genotype and allele frequencies as well (two tailed Fisher’s exactP >0.05).ConclusionOur results showed that Gly82Ser polymorphism in RAGE gene was not associated with diabetic microangiopathy,which suggests that these genetic variants may not be involved in the mechanism of diabetic microangiopathy in Chinese type 2 diabetics.
