Arnold-Chiari malformation

The chain reaches the human disease Chiari malformation type I, which Mondo defines as: “Arnold-Chiari malformation type I is a central nervous system malformation characterized by caudal displacement of the cerebellar tonsils exceeding 5mm below the foramen magnum with or without syringomyelia. Symptoms vary in onset and severity and include suboccipital headache, neck pain, vertigo, tinnitus, ocular symptoms (diplopia, blurred vision, photofobia, nystagmus), lower cranial nerve signs, cerebellar ataxia, and spasticity. Some affected individuals can be asymptomatic.” It reaches 1 more human disease, 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 6 species entries marked as a defect.

  2. Human disease

    Reached

    2 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.

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.

Mondo disease Name Found by
MONDO:0007316 Chiari malformation type I Arnold-Chiari malformation type I is a central nervous system malformation characterized by caudal displacement of the cerebellar tonsils exceeding 5mm below the foramen magnum with or without syringomyelia. Symptoms vary in onset and severity and include suboccipital headache, neck pain, vertigo, tinnitus, ocular symptoms (diplopia, blurred vision, photofobia, nystagmus), lower cranial nerve signs, cerebellar ataxia, and spasticity. Some affected individuals can be asymptomatic. OMIA's OMIM numbers
MONDO:0008816 Chiari malformation type II Arnold-Chiari malformation type II is a rare, central nervous system malformation characterized by caudal displacement of the cerebellum, pons, medulla and fourth ventricle through the foramen magnum into the spinal canal, and is typically associated with myelomeningocele. Variable other central nervous system abnormalities might be present (partial or complete agenesis of the corpus callosum, a small fourth ventricle, obstructive hydrocephalus, falx and tentorium defects, and polygyria). Symptoms include hypotonia, apnea with cyanosis, dysphagia, opisthotonus, nystagmus, spasticity, ataxia, and occipital headache. OMIA's OMIM numbers
