Hemochromatosis, Type 2a; Hfe2a

Description

Juvenile, or type 2, hemochromatosis is an autosomal recessive inborn error of iron metabolism that leads to severe iron loading and organ failure before 30 years of age. The common complications of iron overload, including liver cirrhosis, cardiac disease, endocrine failure, diabetes, arthropathy, and skin pigmentation, are similar to those of adult-onset hereditary hemochromatosis, but hypogonadism and cardiomyopathy are the most common symptoms at presentation. Heart failure and/or major arrhythmias are usually the cause of death in the absence of treatment. Early detection of the disorder is important because iron depletion by phlebotomy can prevent organ damage and all disease manifestations (summary by Roetto et al., 1999). Genetic Heterogeneity of Hemochromatosis Type 2Hemochromatosis type 2B (HFE2B ) is caused by mutation in the hepcidin gene (HAMP ) on chromosome 19q13.
