Aliases: cblA.
ai-gene-review has this gene at status INITIALIZED; the description is shown only once the review is complete. Read the draft upstream.
Relationship is the entry's genetic[].relationship_type. untyped means the entry has a genetic record for the gene but does not type it; its free-text association is shown instead.
| Disorder | Relationship | Where the gene appears |
|---|---|---|
| Methylmalonic Acidemia | causative |
mechanism: MMUT/AdoCbl pathway molecular function deficiency
subtype: Vitamin B12-responsive methylmalonic acidemia

An entry matches when ClinGen's MONDO disease is the entry's own disease term, a subtype term, or an exact-match mapping. An amber status marks an entry ClinGen supports the gene for (Definitive, Strong or Moderate) whose own record does not type it. A Limited, Disputed or Refuted tier on such an entry is not a gap.
