• Type 2 diabetes mellitus
• EC-SOD
• polymorphism
• haplotype
• environmental factors

We aimed to investigate whether the EC-SOD rs2536512, rs8192291 and rs1799895 polymorphisms and haplotypes are associated with T2DM in a Chinese Han population. A total of 540 Chinese Han patients with T2DM and 562 healthy subjects were enrolled in our study since October 2013, and all of them had no blood relationship. An iPlex GLOD SNP genotyping analysis of the EC-SOD rs2536512, rs8192291 and rs1799895 was carried out in a 384 well plate format using the Sequenom MassARRAY (R) System (Sequenom, Inc. San Diego, USA). We observed that the CT (OR=1.58, 95% CI=1.20-2.08) and TT (OR=15.27, 95% CI=4.34-53.75) genotypes of rs8192291 were associated with T2DM susceptibility compared with the CC genotype. In dominant and recessive models, rs8192291 was correlated with a moderate statistically increased susceptibility of T2DM compared with the reference genotype. The GTC, GCC and GCG haplotypes were associated with risk of T2DM. In summary, rs8192291 polymorphism and haplotypes may become a useful biomarker for prediction of the susceptibility of this disease. Further experiments are necessary to validate our results.
