摘　　要：Background： Four single nucleotide polymorphisms （SNPs） in the modulator recognition factor 2/AT-rich interaction domain 5B （MRF2/ARID5B） gene located at chromosome 10q21,2 have been shown to be associated with both type 2 diabetes mellitus （T2DM） and coronary artery disease in a Japanese cohort. This study aimed to investigate the relationship between these SNPs （rs2893880, rs10740055, rs7087507, rs10761600） and new-onset T2DM and lipid metabolism in a Northern Chinese population. Methods： This was a case-control study. The rs2893880, rs10740055, rs7087507, and rs10761600 genetic variants were genotyped by SNPscan and analyzed in relation to T2DM susceptibility in 2000 individuals （090 with newly diagnosed T2DM and 1001 controls without diabetes mellitus）. Associations between the MRF2/ARID5B genetic models and T2DM were determined by multivariate logistic regression. Results： Regarding the rs 10740055 SNP, AA was associated with a higher risk of T2DM compared with codominant-type CC （adjusted by sex, age, and body mass index [BMI], P = 0.041, odds ratio [OR] = 1.421, 95% confidence interval [C1 ] 1.014-1.991）. Meanwhile, AA individuals were at increased risk of presenting with T2DM compared with individuals with CC or a single C （adjusted by sex, age, and BMI, P = 0.034, OR = 1.366, 95% CI 1.023-1.824）. With respect to rsl0761600, AT contributed to a higher risk of T2DM compared with AA （adjusted by sex, age, and BMI, P = 0.013, OR = 1.585, 95% CI 1.101-2.282）, while TT also increased the risk of presenting with T2DM compared with AA or A （adjusted by sex, age, and BMI, P = 0.004, OR = 1.632, 95% CI 1.166-2.284）. High-density lipoprotein cholesterol （HDL-C） levels were significantly different among the three genotypes of rs7087507 in the controls （P = 0.048） （GG〉GA）. Conclusions： The present results identified MRF2/AR1D5B as a potential susceptibility gene for new-onset T2DM in a Northern Chinese population, while the rs7087507 SNP was associated with HDBackground： Four single nucleotide polymorphisms （SNPs） in the modulator recognition factor 2/AT-rich interaction domain 5B （MRF2/ARID5B） gene located at chromosome 10q21,2 have been shown to be associated with both type 2 diabetes mellitus （T2DM） and coronary artery disease in a Japanese cohort.
