Objective To identify the important risk factors for type 2 Diabetes Mellitus(T2 DM) and develop effective strategies to address the problem of T2 DM. Our study aimed to evaluate the association between apolipoprotein E(Apo E) genetic polymorphism and type 2 diabetes, and to provide clues for the etiology of T2 DM.Methods Based on the criteria of inclusion and exclusion, we extracted, pooled, analyzed and assessed the case-control studies of Apo E polymorphism and T2 DM published in Pub Med, Web of Science,Medline, Wan Fang, VIP, and CNKI databases by R soft-ware(version 3.4.3). We used Random-effect models when heterogeneity was present in between-study, and fixed-effect models otherwise.Results We had 59 studies covering 6,872 cases with T2 DM and 8,250 controls, and compared the alleles and genotypes of Apo E between cases and controls. When we conducted a comparison between Apo E ε4 and ε3 alleles, we produced a pooled OR of 1.18(95% CI: 1.09-1.28;P < 0.001). Apo E ε2/ε2 genotype displayed a possible association with T2 DM(OR = 1.46;95% CI: 1.11-1.93;P = 0.007), ε3/ε4 genotype showed a 1.11-fold risk(OR = 1.11;95% CI: 1.01-1.22;P = 0.039) and ε4/ε4 genotype had a1.71-fold risk of developing T2 DM(OR = 1.71;95% CI: 1.33-2.19;P < 0.001) when they were compared with ε3/ε3 genotype.Conclusions There is an association between Apo E polymorphism and T2 DM: allele ε4 and genotypes(ε2/ε2, ε3/ε4, and ε4/ε4) are associated with the increased risk for the development of T2 DM, and they may be risk factors for T2 DM.
