Hepatoerythropoietic porphyria is a very rare form of hepatic porphyria caused by a disorder in both genes which code Uroporphyrinogen III decarboxylase (UROD).It has a similar presentation to porphyria cutanea tarda (PCT) but with earlier onset. In classifications which define PCT type 1 as sporadic and PCT type 2 as familial hepatoerythropoietic porphyria is more similar to type 2.
