Management of Patients With Erythropoietic Protoporphyria–Related Progressive Liver Disease

Abstract

Erythropoietic protoporphyria (EPP) is an inherited metabolic disorder of heme synthesis resulting from overproduction of protoporphyrin IX (PPIX), which can lead to progressive liver disease characterized by recurrent EPP crises and end-stage liver disease.
