Haemochromatosis, also spelled hemochromatosis, is a hereditary disease characterized by improper dietary iron metabolism (making it an iron overload disorder), which causes the accumulation of iron in a number of body tissues. Iron accumulation can eventually cause end organ damage, most importantly in the liver and pancreas, manifesting as liver failure and diabetes mellitus respectively. It is estimated that roughly one in every 300-400 people is affected by the disease, primarily of Northern European and especially people of Irish, Scottish, Welsh and English descent. ...

Hemochromatosis also refers to the concept of hereditary hemochromatosis, in which certain genetic mutations can predispose people to iron accumulation. However, the two are not always related; not all cases of iron overload are associated with genetic causes, and having such hereditary markers does not necessarily cause significant iron overload.
