Hemochromatosis type 2 is a disease in which too much iron builds up in the body.  This extra iron is toxic to the body and can damage the organs.[1] Type 2 hemochromatosis is a juvenile-onset disorder. Iron accumulation begins early in life, and symptoms may begin to appear in childhood. Hemochromatosis is inherited in an autosomal recessive manner. It is caused by a mutation in the HAMP or HFE2 gene.[2]

Hemochromatosis may be aquired or inherited. Hereditary hemochromatosis is classified by type depending on the age of onset and other factors such as genetic cause and mode of inheritance.[2] To learn more about other types click on the disease names below:
