Juvenile hemochromatosis

Juvenile hemochromatosis (or hemochromatosis type 2) is, as its name indicates, a form of hemochromatosis which emerges during youth.

There are two forms:
 * "HFE2A" is associated with hemojuvelin
 * "HFE2B" is associated with hepcidin antimicrobial peptide

Some sources only specifically include hemojuvelin as a cause of juvenile hemochromatosis.
