SummaryThe porphyrias are clinically variable and genetically heterogeneous, predominantly hereditary metabolic diseases, which are caused by a dysfunction of specific enzymes in heme biosynthesis. Here, we provide an overview of the etiopathogenesis, clinic, differential diagnosis, laboratory diagnostics and therapy of these complex metabolic disorders and cover in detail the most common form of porphyria worldwide (porphyria cutanea tarda), the most frequent childhood porphyria (erythropoietic protoporphyria), and the most common neurocutaneous porphyria (variegate porphyria).

Wir geben einen Überblick zur Ätiopathogenese, Klinik, Differenzialdiagnose, Labordiagnostik und Therapie dieser komplexen Stoffwechselkrankheiten und stellen die weltweit häufigste Porphyrieform (Porphyria cutanea tarda), die häufigste Porphyrie des Kindesalters (erythropoetische Protoporphyrie) und die häufigste neurokutane Porphyrie (Porphyria variegata) detailliert vor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
