GTR Home > Conditions/Phenotypes > Congenital erythropoietic porphyria


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). [from OMIM]
