Hemojuvelin (HJV)-associated hemochromatosis: analysis of HJV and HFE mutations and iron overload in three families.

Juvenile hemochromatosis is a severe form of hereditary iron overload. It can be caused by mutations in either hepcidin or hemojuvelin genes. In this study we identified the molecular basis of juvenile hemochromatosis in three Australian families and assessed the role of potential modifying genes in individuals carrying HFE mutations.
