Erythropoietic porphyria (EP) is a rare inborn error of porphyrin-heme synthesis inherited that is as an autosomal recessive trait. Congenital erythropoietic porphyria (CEP; OMIM #, also called Günther disease) is a rare, autosomal recessive porphyria. It results from. Gunther disease, also known as congenital erythropoietic porphyria (CEP), uroporphyrinogen III synthase deficiency and UROS deficiency, is a congenital form.

Blistering and scarring of exposed areas may lead to mutilating deformity. Genotype-Phenotype Correlations The genotype-phenotype correlations that have been established in CEP are largely determined by the amount of residual enzyme activity encoded by the specific mutated alleles.

In more severe cases, other symptoms can include a low level of red blood conegnital anemiaenlargement of the spleen, and increased hair growth hypertrichosis. Isomer I porphyrinogens are pathogenic when they accumulate in large amounts and are auto-oxidized to their corresponding porphyrins [ Piomelli et alPoh-Fitzpatrick et al ].
Prognosis In severe forms hemolytic anemia and, in particular, thrombocytopenia dominate the prognosis and greatly diminish the life expectancy of patients. Deposition of porphyrins may lead to corneal ulcers and scarring, which can ultimately lead to blindness.

Etiology Congenital erythropoietic porphyria is caused by a deficiency of uroporphyrinogen- synthase URO-S; the fourth enzyme in the heme biosynthesis pathway leading to a massive accumulation of isomeric I porphyrins uro and coproporphyrins in the bone marrow. While most centers would consider decisions regarding prenatal testing to be the choice of the parents, discussion of these issues is appropriate. Government funding, and some supported by private industry, are posted on this government web site.
The parents of an individual with an autosomal recessive disorder both carry one copy of the defective gene, but usually do not experience any signs or symptoms of the disorder.
