Hereditary Hemochromatosis is an autosomal recessive disease, characterized by chronic iron overload. It is mainly due to mutations of the HFE-1 gene. In the large majority of patients, the substitution of tyrosine for cysteine at amino acid 282 (C282Y) is found at the homozygous state. Since the HFE-1 hemochromatosis identification, several other entities of iron overload have been individualized. In the present article, the frequency, penetrance and pathophysiology of HFE-1 hemochromatosis as well as various clinical presentations resulting from different mutations affecting different proteins involved in iron metabolism are described.
