obsolete chronic hepatic porphyria
MONDO:0019800
OBSOLETE. Chronic hepatic porphyrias represent a sub-group of porphyrias. They are characterized by bullous photodermatitis caused by a deficiency of uroporphyrinogen decarboxylase (URO-D; the fifth enzyme in the heme biosynthesis pathway). Chronic hepatic porphyria encompasses two diseases: porphyria cutanea tarda and hepatoerythropoietic porphyria (extremely rare).
