Abstract

Juvenile or type2 hemochromatosis is a rare autosomal recessive disorder which leads to severe iron overload early in life. As in the classic adult form of the disease iron toxicity causes liver cirrhosis, cardiomyopathy, and endocrine complications, but the onset of the disease is anticipated in the second to third decades of life. Experience of this disease in children is limited. Molecular diagnosis is unfeasible because the type2 hemochromatosis gene is still unknown, although it is known that the disease locus maps to chromosome1q. Combining linkage analysis with markers encompassing chromosome1 locus and a non-invasive method for liver iron quantitation we diagnosed juvenile hemochromatosis in a presymptomatic stage in an 11-year-old Italian child. A regular phlebotomy protocol reduced iron overload preventing all the disease complications. Conclusion: Juvenile hemochromatosis patients have severe iron overload within the first years of life, strengthening the greater iron absorption that occurs in this as compared to other types of hemochromatosis. Early detection is essential, because treatment in presymptomatic stages prevents organ damage.
