Hepcidin antimicrobial peptide

The protein product encoded by the HAMP gene, hepcidin, is an important regulator of iron metabolism. It is involved in both iron storage in macrophages and iron absorption by enterocytes.Mutations of the gene cause juvenile hemochromatosis (type 2B) often in a digenic fashion with an additional HFE1 mutation.
