MSH: 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.,CSP: autosomal recessive porphyria characterized by splenomegaly, photosensitivity, hemolytic anemia, and the appearance of red urine in early infancy; results from increased synthesis of uroporphyrinogen I relative to uroporphyrinogen III in bone marrow normoblasts.,NCI: A rare congenital metabolic disorder characterized by an inborn error of porphyrin-heme biosynthesis. It is caused by deficiency of the enzyme uroporphyrinogen III cosynthetase. It results in cutaneous photosensitivity leading to blistering and scarring of the exposed skin areas.
