OMIA group 3085

Leukodystrophy, hypomyelinating, GJC2-related

The chain reaches the human disease hereditary spastic paraplegia 44, which Mondo defines as: “A very rare, complex form of hereditary spastic paraplegia characterized by a late-onset, slowly progressive spastic paraplegia associated with mild ataxia and dysarthria, upper extremity involvement (i.e. loss of finger dexterity, dysmetria), and mild cognitive impairment, without the presence of nystagmus. A hypomyelinating leukodystrophy and thin corpus callosum is observed in all cases and psychomotor development is normal or near normal. SPG44 is caused by mutations in the GJC2 gene (1q41-q42) encoding the gap junction gamma-2 protein.” It reaches 2 more human diseases, listed below.

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.

  1. Animal disease

    Reached

    OMIA records it in 1 species entry marked as a defect.

  2. Human disease

    Reached

    3 Mondo diseases.

  3. Human gene

    Stopped here

    No gene of a species entry marked as a defect reaches a human gene through Ensembl's orthologs.

  4. Target evidence

    Not reached

    The chain stopped before this step.

  5. Drugs

    Not reached

    The chain stopped before this step.

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.

Species

The chain follows only the species entries that OMIA marks as a defect.

Species Scientific name OMIA entry A defect
dog Canis lupus familiaris OMIA:003085-9615 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
dog GJC2 gap junction protein gamma 2 NCBI Gene 607294 Ensembl does not know this NCBI Gene identifier.

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.
