title: Correlation between HFE gene polymorphisms and increased risk of coronary artery disease among patients with type 2 diabetes in Iran.
abstract: OBJECTIVE
  Diabetes mellitus is a risk factor for cardiovascular diseases (CVDs), which are among the major causes of deaths in type 2 diabetes (T2D). The purpose of the present study was to determine the association of C282Y and H63D mutations in the HFE gene with increased risk of coronary artery disease (CAD) in T2D patients.
  
  
  METHODS
  Two hundred and ninety individuals were divided into two groups: a case group and a control group. Genomic DNA of peripheral venous blood cells was extracted and the HFE gene mutations were analyzed using the PCR-RFLP technique.
  
  
  RESULTS
  Data analysis revealed a significant difference between the allele frequencies of H63D and C282Y mutations between the case group and the controls (P < 0.05). The relationships between the GA and GG genotypes in C282Y and H63D mutations in terms of fasting blood sugar (FBS), lipid profile (total cholesterol, triglycerides, high-density lipoproteins (HDL), low-density lipoproteins), body mass index (BMI), HbA1c, micro albuminuria, and creatine levels did not show a significant differences between the two groups (P > 0.05). Using a logistic regression model, BMI, FBS, HDL, and total cholesterol levels were significantly different with independent predictors of CVD (P < 0.05).
  
  
  CONCLUSIONS
  Our results revealed a significant correlation between C282Y and H63D mutations and the development of CAD in T2D patients.
