Congenital erythropoietic porphyria: a single-observer clinical study of 29 cases

Abstract

CEP is a multisystem disease; cutaneous, ocular, oral and skeletal manifestations also contribute to disease severity and impact on HRQoL, in addition to the haematological complications. The rarity of the disease can lead to delayed diagnosis. The lack of consistent genotype-phenotype correlation in CEP suggests a contribution to phenotype from other factors, such as environment, patients' photoprotective behaviour and genes other than UROS. There is currently an unmet need for multidisciplinary management of patients with CEP.
