OMIA group 1175
Porphyria, congenital erythropoietic
The chain reaches the human disease congenital erythropoietic porphyria, which Mondo defines as: “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.”
The chain
From the animal disease to the drugs. The page shows what each step found and where the chain stopped. It does not say whether the animal is a model of a human disease.
-

OMIA records it in 4 species entries marked as a defect.
-
Human disease
Reached
1 Mondo disease.
-

Drugs
Stopped here
No ChEMBL drug acts on a human gene of the group's target evidence.
The chain stopped at Drugs: No ChEMBL drug acts on a human gene of the group's target evidence.
Natural-model score
How complete and how well supported the chain to each human disease is, out of 100, by stated rules. It does not say that the animal is a validated model of the human disease. How the score works.
89.8 out of 100
| Part | Computed from | Points |
|---|---|---|
| Target evidence | Open Targets score of 0.85 | 29.8 of 35 |
| Drugs | A drug has reached approved for this disease | 25.0 of 25 |

Species
The chain follows only the species entries that OMIA marks as a defect.
| Species | Scientific name | OMIA entry | A defect |
|---|---|---|---|
| domestic cat | Felis catus | OMIA:001175-9685 | Yes |
| domestic cattle | Bos taurus | OMIA:001175-9913 | Yes |
| pig | Sus scrofa | OMIA:001175-9823 | Yes |
| zebu cattle | Bos indicus | OMIA:001175-9915 | Yes |
Genes
Each gene OMIA records for a species entry, and the human gene it reaches through Ensembl's orthologs.
| Species | Animal gene | Human gene | Ortholog |
|---|---|---|---|
| domestic cat | UROS uroporphyrinogen III synthase NCBI Gene 100500740 | UROS Ensembl | one to one |
| domestic cattle | No gene | OMIA records no gene for this species entry. | |
| pig | No gene | OMIA records no gene for this species entry. | |
| zebu cattle | No gene | OMIA records no gene for this species entry. | |
Human diseases
Two routes lead from an OMIA group to a Mondo human disease: OMIA's own Mondo link, and the group's OMIM numbers through Mondo's cross-references.
- OMIA's own Mondo link: OMIA links the group to no Mondo disease.
- OMIA's OMIM numbers: found a disease.
