The aim of the study was to investigate the relationship between I27L variant of HNF-loc gene and type 2 diabetes mellitus [T2DM] in an/the oriental population. We recruited 149 T2DM patients and 96 non-diabetes controls from China. The I27L polymorphism in HNF-la gene was detected by PCR-RFLP analysis. A mete-analysis of previously published studies on I27L and T2DM of orient population and our new study was performed. Databases of MEDLINE, CBM, and the Cochrane Library [CD-ROM] were electronically searched from January 1980 to April 2008. Analysis was performed by RevMan 4.2 software which was downloaded from website of Cochrane collaboration. [1]. The genotype distribution of I27L/exonl polymorphism in the HNF-loe gene was in Hardy-Weinberg equilibrium [chi[2] = 2.34, 0.05 < P< 0.1]. The IL, LL genotype frequencies and L allelic frequency were slightly higher in T2DM group than in controls [0.52, 0.14 and 0.40 in T2DM vs. 0.49, 0.08 and 0.33 in controls], but the difference were not statistically significant, which indicated that 27L variant did not increase the risk of T2DM in our small sample Chinese population. [2]. Three published studies concerning the Chinese population, two studies involving the Japanese population and our present study, providing information on a total of 1225 unique subjects, were included in the meta-analysis. The results showed that the 271 variant increased the prevalence of T2DM [OR 1.22, 95% CI 1.03-1.44, p = 0.02]. I27L polymorphism in the HNF-1 alpha gene increases the risk of T2DM in the orient population [Chinese and Japanese]
