Objective: Uncoupling protein 2 (UCP2) is a regulator of insulin secretion, free fatty acid (FFA) concentrations, and lipid metabolism that plays crucial roles in energy homeostasis. This study aimed to investigate the association of 45-bp ins/del polymorphism of UCP2 and susceptibility to NAFLD and T2DM. DNA was extracted from the white blood cells of the subjects and the gene polymorphism was determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). In this study, 72 patients with NAFLD, 71 healthy individuals as control, 80 patients with T2DM, and 77 age/race matched healthy controls were enrolled in the study.
Results: A higher prevalence of insertion/insertion genotype has been observed in T2DM patients compared with the control group (p value˂ 0.05). But, there was no difference in genotype distribution between NAFLD patients and control groups (p value> 0.05). NAFLD patients with D/D, D/I genotype had higher triglyceride, ALT and AST levels, and lower HDL level than healthy controls. Patients with T2DM with D/D or D/I genotype also had significantly higher fasting serum glucose (FSG) level. While we found an association between the 45bp I/D polymorphism in 3ʹUTR of UCP2 and T2DM, no any correlation between this polymorphism and NAFLD was identified.
