Abstract:
Objective To investigate the relationship between polymorphisms of candidate genes 〔glucokinase (GCK) gene, NIDDM1(D2S140) gene, fatty acid bindingprotein2(FABP2)gene〕and type 2 diabetes mellitus (DM) in Shandong Chinese Han population. Methods Short tandem repeat (STR) region polymorphisms of GCK gene, NIDDM1 gene and FABP2 gene were analyzed with the polymerase chain reaction and polyacrylamide sequencing gel in 107 patients with type 2 diabetes mellitus and 105 normal subjects. The subjects studied were unrelated and they are Chinese Hans living in Shandong province and no diabetes family history was revealed. Results A5 allele of GCK gene and B2 allele of NIDDM1 gene were positively related with type 2 diabetes (RR=15.70, P0.05). Logistic regression analysis showed that A5 allele and B2 allele were among the risk factors of type 2 diabetes. Conclusion Polymorphic microastellite repeat markers at the glucokinase gene and the NIDDM1 (D2S140) gene locus are associated with type 2 diabetes in Chinese. The polymorphism at the FABP2 locus is not a genetic marker for type 2 DM in Chinese Hans.
