    • "We may speculate that the disagreement between the findings of cross-sectional studies and prospective studies might be due to a survival bias in the cross-sectional studies. The C282Y heterozygous frequencies in diabetics in our study (9% in CAD group and 8.2% in the control group) were similar to other European reports (Njajou et al., 2002). Different populations represent different gene pools, suggesting that gene-disease associations can be expected to vary between populations. "

    ABSTRACT: Iron metabolism might be involved in the pathogenesis of CAD, and C282Y and H63D mutations in the HFE gene are associated with increased serum iron levels and net iron accumulation. The aim of this study was to look for a relationship between the C282Y and H63D gene mutations of the HFE gene and coronary artery disease (CAD) in a group of patients with type 2 diabetes lasting more than 10 years. The C282Y and H63D gene mutations were tested in 338 Caucasians with type 2 diabetes: 156 cases with CAD and 182 subjects with no history of CAD. The C282Y and the H63D HFE gene distributions in patients with CAD (C282Y: YY 0.6%, CY 9.0%, CC 90.4%; H63D: DD 3.8%, HD 21.8%, HH 74.4%) were not significantly different from those of diabetic subjects without CAD (C282Y: YY 0%, CY 8.2%, CC 91.8%; H63D: DD 2.2%, HD 20.3%, HH 77.5%). In conclusion, we failed to demonstrate that the C282Y and H63D HFE gene mutations were risk factors for CAD in Caucasians with type 2 diabetes lasting longer than 10 years.

    ABSTRACT: Diabetes mellitus is a recognized consequence of hereditary haemochromatosis. Whether the common HFE mutations, that associate with this condition and pre-dispose to increases in serum iron indices, are over-represented in diabetic populations remains controversial. We present data from the largest case-control study of the C282Y and H63D HFE allele frequencies in typical type 2 diabetes mellitus, as defined by an age of onset greater than 30 years and no requirement for insulin in the first year post-diagnosis. We also present a meta-analysis of all similar studies to date. We see no evidence for over-representation of iron loading HFE alleles in type 2 diabetes mellitus, suggesting that screening for HFE mutations in this population is of no value.
