Hereditary hemochromatosis is an autosomal recessive disorder associated with the mutation of the HFE gene. C282Y and H63D mutations in this gene have been described. Hereditary hemochromatosis is primarily associated with the C282Y mutation; the importance of H63D is not well known. In previously reported studies, the C282Y mutation was not detected in Turkey. We herein present a family in whi...

A 66-year-old male patient presented with a 4-month history of progressive muscle weakness. Twelve years prior to presentation he was evaluated for fatigue, weight loss, new-onset diabetes and elevated liver enzymes and was diagnosed with hereditary hemochromatosis, homozygous for the C282Y mutation in the HFE gene. His total iron at diagnosis was 137 mcg/dL; iron binding capacity, 149 mcg/dL; ...

Hereditary hemochromatosis is an iron-overload disorder resulting from mutations in proteins presumed to be involved in the maintenance of iron homeostasis. Mutations in hemojuvelin (HJV) cause severe, early-onset juvenile hemochromatosis. The normal function of HJV is unknown. Juvenile hemochromatosis patients have decreased urinary levels of hepcidin, a peptide hormone that binds to the cellu...

Hereditary hemochromatosis is most commonly caused by homozygosity for a point mutation (C282Y) in the human hemochromatosis gene (HFE). The mechanism by which HFE regulates iron absorption is not known, but the C282Y mutation results in loss of cell surface expression of the human hemachromatosis protein (HFE) and hyperabsorption of iron by the duodenal enterocyte. Mice homozygous for a deleti...
