Discovery of the hemochromatosis gene will require rethinking the regulation of iron metabolism.

Abstract excerpt

The identity of the protein responsible for hemochromatosis, the iron overload disease, has eluded scientists for years. However, a recent report identifies the gene where the hemochromatosis defect lies. It is a gene that encodes a major histocompatibility complex (MHC) class-1-like protein called HLA-H. The mechanism by which an HLA-H defect alters iron metabolism is still unidentified. However, this new...
