Hereditary hemochromatosis is an autosomal recessive disorder that disrupts the body's regulation of iron. It is the most common genetic disease in whites. Men have a 24-fold increased rate of iron-overload disease compared with women. Persons who are homozygous for the HFE gene mutation C282Y comprise 85 to 90 percent of phenotypically affected persons. End-organ damage or clinical manifestati...
AIM In chronic hepatitis C, iron might play an important role as a hepatotoxic co-factor. Therefore, venesection, a standard treatment for hemochromatosis, has been proposed as an alternative for patients who respond poorly to anti-viral therapy. To improve our understanding of iron-induced hepatotoxicity, we compared the responses to venesection between patients with chronic hepatitis C and th...
Juvenile hemochromatosis is a rare autosomal recessive disorder that typically occurs in the first to third decades of life. Its symptoms are more acute and severe than classic hemochromatosis. We describe a 27-year-old man who was referred to the gastrointestinal clinic with a probable diagnosis of fatty liver and was finally diagnosed as having juvenile hemochromatosis. A review of the scient...

The term hemochromatosis encompasses at least four types of genetic iron overload conditions, most of them recently distinguished from one another as a result of the identification of a series of genes related to iron metabolism. At least three of these entities (HFE hemochromatosis, juvenile hemochromatosis and transferrin receptor 2 hemochromatosis) involve systemic hepcidin deficiency as a k...
The frequencies of different HLA-A and -B alleles in 77 Australian patients with hemochromatosis have been compared with frequencies of HLA alleles not associated with hemochromatosis in 63 of their heterozygous relatives and with published population frequencies. As for all other populations reported, an association of HLA-A3 and HLA-B7 with the disease was found. A weak association with HLA-B...
