|Also known as Hemojuvelin (Hemochromatosis type 2 protein homolog) (RGM domain family member C). |
HFE2: Member of the repulsive guidance molecule (RGM) family. Involved in iron metabolism. Acts as a bone morphogenetic protein (BMP) coreceptor. Enhancement of BMP signaling regulates hepcidin (HAMP) expression and iron metabolism. May cooperate with hepcidin to restrict iron absorption in the gut.
Could represent the cellular receptor for hepcidin. Defects in HFE2 are the cause of hemochromatosis type 2A (HFE2A); also known as juvenile hemochromatosis (JH). HFE2A is an early-onset autosomal recessive disorder due to severe iron overload resulting in hypogonadotrophic hypogonadism, hepatic fibrosis or cirrhosis and cardiomyopathy, occurring typically before age of 30. It is the consequence of intestinal iron hyperabsorption associated with macrophages that do not load iron. Deleterious mutations of HFE2 reduced HAMP (hepcidin) levels despite iron overload, which normally induces HAMP expression. Belongs to the repulsive guidance molecule (RGM) family. 3 isoforms of the human protein are produced by alternative splicing.
