The chain reaches the human disease methylmalonic acidemia due to transcobalamin receptor defect, which Mondo defines as: “Methylmalonic aciduria due to transcobalamin receptor defect is a rare metabolite absorption and transport disorder characterized by a moderate increase of methylmalonic acid (MMA) in the blood and urine due to decreased cellular uptake of cobalamin resulting from decreased transcobalamin receptor function. Patients are usually asymptomatic however, screening reveals increased C3-acylcarnitine and MMA in plasma. Serum homocysteine levels may vary from normal to moderately elevated and retinal vascular occlusive disease, resulting in severe visual loss, has been reported.”
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.
-
Animal disease
Reached
OMIA records it in 1 species entry marked as a defect.
-
Human disease
Reached
1 Mondo disease.
-
Human gene
Stopped here
No gene of a species entry marked as a defect reaches a human gene through Ensembl's orthologs.

The chain stopped at Human gene: No gene of a species entry marked as a defect reaches a human gene through Ensembl's orthologs.
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.
9.0 out of 100
| Part | Computed from | Points |
|---|---|---|
| Target evidence | No Open Targets association with this disease | 0.0 of 35 |
| Drugs | No drug has been tested for this disease, and none acts on its genes | 0.0 of 25 |
| Ortholog | No gene of a naturally occurring entry reaches a human gene | 0.0 of 20 |
| Both routes | One route found this disease | 5.0 of 10 |
| Species | 1 naturally occurring species entry marked as a defect | 4.0 of 10 |
Species
The chain follows only the species entries that OMIA marks as a defect.
| Species | Scientific name | OMIA entry | A defect |
|---|---|---|---|
| chicken | Gallus gallus | OMIA:001299-9031 | 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 |
|---|---|---|---|
| chicken | CD320 CD320 molecule NCBI Gene 420066 | No human ortholog in Ensembl. | |
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.
