To determine whether the HFE gene variants H63D and C282Y are associated with NAFLD in persons with type 2 diabetes, we conducted a case-control study including 145 case of NAFLD patients with a history of type 2 diabetes and 145 matching control. The genomic DNA was extracted from the peripheral venous blood and the genotyping of HFE gene mutations was analyzed using the PCR-RFLP technique. Statistical analysis was performed using SPSS 12.0 software by χ2 test, t test and ANOVA (P < 0.05). Data showed no increased frequency of HFE mutations in persons with type 2 diabetes and no association between H63D mutation and NAFLD in the study population. Also, we analyzed index of physiological variables including FBS, lipid profile (TC, TG, LDL-C, and HDL-C), BMI, HbA1c, and micro albuminuria and Cr levels). Data showed there are no relationship between these indexes and HFE gene mutations and either NAFLD as a complication of diabetes. But our results showed a relationship between C282Y mutation and NAFLD in persons with type 2 diabetes. C282Y mutation might be a genetic marker of NAFLD in Iranian population.
