Juvenile hemochromatosis (JH) or type 2 hereditary hemochromatosis, is a rare condition affecting about 1 in 4.8 million people [6] and results from autosomal recessive loss-of-function mutations in either the HJV (type 2a) or HAMP (type 2b) genes. This evidence concerns the gene HAMP and hemochromatosis type 2.
