OMIA group 1821
Coat colour, albinism, oculocutaneous type IV
The chain reaches the human disease oculocutaneous albinism type 4, which Mondo defines as: “Oculocutaneous albinism type 4 (OCA4) is a type of OCA characterized by varying degrees of skin and hair hypopigmentation, numerous ocular changes and misrouting of the optic nerves at the chiasm.”
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.
-

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.

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: found a disease.
- OMIA's OMIM numbers: found a disease.
| Mondo disease | Name | Found by |
|---|---|---|
| MONDO:0011683 | oculocutaneous albinism type 4 Oculocutaneous albinism type 4 (OCA4) is a type of OCA characterized by varying degrees of skin and hair hypopigmentation, numerous ocular changes and misrouting of the optic nerves at the chiasm. | Both routes |
Target evidence
Each Open Targets association between one of the group's human genes and one of its human diseases, with its overall score and the score for each kind of evidence.
| Human gene | Human disease | Score | Evidence | Kinds of evidence |

| AMACR | oculocutaneous albinism type 4 | 0.01 | 2 | Literature 0.06 |
Drugs
No ChEMBL drug acts on a human gene of the group's target evidence.
