    Abstract:
    Abstract Background: Hereditary hemochromatosis (HH) is characterized by an increased intestinal absorption of iron due to mutations in iron-related genes. The C282Y and H63D mutations of the HFE gene are principally responsible for HFE-related hemochromatosis. The majority of HH cases are reported in Western countries where HFE-related mutations are common. The prevalence of HFE-related mutations is not yet clear in eastern Turkey. We aim to clarify the frequency of HFE gene mutations in men who live in eastern Turkey and also assess the biochemical effects of the H63D mutation. Methods: Using the reverse hybridization Hemochromatosis Strip Assay A (ViennaLab, Profiblot T-48, Tecan), DNA extracted from the blood samples of 159 healthy men was analyzed for different mutations in the HFE gene. Results: The H63D mutation was found with an overall carrier frequency of 5.6% (7% heterozygous and 2% homozygous). We also noted that the C282Y gene mutation was not detected in the study. In subjects with the H63D mutation, there were significantly elevated levels both of serum iron and transferrin saturation (p<0.05). Other hematologic and biochemical tests were in the normal ranges in H63D-positive subjects. Conclusions: A lack of C282Y mutations has been reported as a basic finding for non-Western countries and Turkey. H63D mutations in the HFE gene may cause higher levels of serum iron and transferrin saturation. Both may be useful as simple screening tools for HH.
