Erythropoietic porphyria (EP) is a rare inborn error of porphyrin-heme synthesis inherited that is as an autosomal recessive trait. Congenital erythropoietic porphyria (CEP; OMIM #, also called Günther disease) is a rare, autosomal recessive porphyria. It results from. Gunther disease, also known as congenital erythropoietic porphyria (CEP), uroporphyrinogen III synthase deficiency and UROS deficiency, is a congenital form.
