Preferred Label : Porphyria, congenital erythropoietic;
Symbol : CEP;
CISMeF acronym : CEP;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Uroporphyrinogen III synthase deficiency; Gunther disease; Uros deficiency;
Description : The porphyrias are diseases caused by defects in heme synthesis, resulting in the
accumulation and increased excretion of porphyrins or porphyrin precursors. They are
classified as erythropoietic or hepatic, depending on whether the enzyme deficiency
occurs in red blood cells or in the liver (Gross et al., 2000). Desnick and Astrin
(2002) provided a comprehensive review of congenital erythropoietic porphyria pathogenesis
and treatment. One patient with a phenotype suggestive of congenital erythropoietic
anemia was found to have a mutation in the GATA1 gene (305371.0010) that affected
UROS expression (see XLTT, 314050).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the uroporphyrinogen III cosynthase gene (UROS, 606938.0001);
Laboratory abnormalities : Uroporphyrinogen III cosynthase (URO cosynthase) deficiency in blood and fibroblasts; Uroporphyrin I and coproporphyrin I are found in plasma, red blood cells, urine, and
feces; Pink urine;
