Congenital erythropoietic porphyria (CEP, Günther's disease) is an extremely rare autosomal recessive disease (There have been only 33 case reports in Japan to date.), characterized by mutilating cutaneous photosensitivity and abnormal haem synthesis in the bone marrow. Reduced activity of uroporphyrinogen III synthase (UROIIIS), the fourth enzyme of haem biosynthetic pathway causes this disease. Recent progresses of molecular biology enable us to analyze genetic defect at the molecular level of porphyrias. Also in CEP, it has been reported several reports of mutations of the UROIIIS gene since isolation of a full-length human cDNA encoding UROIIIS by Desnick et al. Here we report about epidemiology, signs and symptoms, laboratory findings and therapies of CEP.

D014576	Uroporphyrinogen III Synthetase	An enzyme that catalyzes the cyclization of hydroxymethylbilane to yield UROPORPHYRINOGEN III and water. It is the fourth enzyme in the 8-enzyme biosynthetic pathway of HEME, and is encoded by UROS gene. Mutations of UROS gene result in CONGENITAL ERYTHROPOIETIC PORPHYRIA.

D017092	Porphyria, Erythropoietic	An autosomal recessive porphyria that is due to a deficiency of UROPORPHYRINOGEN III SYNTHASE in the BONE MARROW; also known as congenital erythropoietic porphyria. This disease is characterized by SPLENOMEGALY; ANEMIA; photosensitivity; cutaneous lesions; accumulation of hydroxymethylbilane; and increased excretion of UROPORPHYRINS and COPROPORPHYRINS.
