[Study on the relationship between sulfonylurea receptor 1 gene polymorphism and type 2 diabetes mellitus].
To study whether the 3c/t polymorphism of the sulfonylurea receptor 1 (SUR1) gene exon16 increased the risk of type 2 diabetes mellitus in type 2 diabetes mellitus pedigrees in Han population in south area of China. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used in 46 type 2 diabetes mellitus pedigrees. The polymorphism in SUR1 was tested and analyzed by Mantel-Haenszel chi(2) test. Frequencies of SUR1-3c/t polymorphism had no significant difference between type 2 diabetes mellitus and normal relatives (genotypes chi(2)=3.224, P=0.199; frequency of allele chi(2)=1.250, P=0.264). In all subjects, type 2 diabetes mellitus and normal relatives, SUR1-3c/t genotypes were listed (cc: 29.3%, 30.2%, 28.3%; ct: 50.7%, 53.8%, 47.2%; tt: 20%, 16.0%, 24.5% respectively). The frequencies of c were 54.7%, 57.1% and 51.9% respectively. The frequency of c is lower than Han population in northern China. The results show that SUR1 exon16-3c/t polymorphism is not associated with type 2 diabetes mellitus in the population.
