cutaneous porphyria
MONDO:0009902
An erythropoietic porphyria (massive accumulation of photoreactive porphyrins in the bone marrow erythroid cells and circulating erythrocytes, resulting in cutaneous photosensitivity) caused by biallelic variants in UROS (in an autosomal recessive inheritance pattern). Cases where biallelic variants reduce WT enzyme activity to <5% are characterized by photosensitivity, hemolytic anemia (often in utero), erythrodontia, splenomegaly, cutaneous blistering, scarring and disfigurement. Other cases where biallelic variants do not reduce enzyme activity as severely (5-12% of WT activity) have a later onset of photosensitivity and milder symptoms.

Gunther disease
Günther disease is a congenital form of erythropoietic porphyria. The word porphyria originated from the Greek word porphura. Porphura actually means "purple pigment", which, in suggestion, the color that the body fluid changes when a person has Gunther's disease. It is a rare, autosomal recessive metabolic disorder affecting heme, caused by deficiency of the enzyme uroporphyrinogen cosynthetase. It is extremely rare, with a prevalence estimated at 1 in 1,000,000 or less. There have been times that prior to birth of a fetus, Gunther's disease has been shown to lead to anemia. In milder cases patients have not presented any symptoms until they have reached adulthood. In Gunther's disease, porphyrins are accumulated in the teeth and bones and an increased amount are seen in the plasma, bone marrow, feces, red blood cells, and urine.
