Spinal intradural arachnoid diverticulum

The chain reaches the human disease spinal intradural arachnoid cysts, which Mondo defines as: “Spinal intradural arachnoid cysts are cerebrospinal fluid -filled sacs that are located between the spinal cord and the arachnoid membrane (one of the three membranes that cover the brain and spinal cord). The signs and symptoms of the condition vary based on the size and location of the cysts. Some affected people may have no suspicious symptoms while others experience progressive back and leg pain; tingling or numbness in the hands or feet; weakness of the legs; and involuntary muscle spasms (spasticity) that result in slow, stiff movements of the legs. When present, symptoms usually occur when the cysts compress the spinal cord or other nearby nerves. Spinal intradural arachnoid cysts are often present at birth and arecaused by developmental abnormalities in the spinal cord that occur during the pregnancy. They can also result from a previous infection or injury and develop later in life. Although there is disagreement in the medical community regarding when to treat spinal intradural arachnoid cysts, the need for treatment generally depends on the size and location of the cyst and whether or not it is causing symptoms. When indicated, the cysts are typically treated with surgery.”

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

    1 Mondo disease.

  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.

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
dog Canis lupus familiaris OMIA:001923-9615 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 No gene OMIA records no gene for this species entry.

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.
