Rare autosomal dominant hereditary hemochromatosis associated with SLC40A1 gene: ferroportin disease or type 4 hereditary hemochromatosis? [PDF]
, 2019 Ferroportin (FPN1), encoded by the SLC40A1 gene, is the unique cellular iron exporter identified in mammals. FPN1 transfers iron from the intestine and macrophages into the bloodstream. This function is negatively regulated by hepcidin.
