Vitamin D-deficiency rickets, type II

The chain reaches the human disease vitamin D-dependent rickets, type 2, which Mondo defines as: “Hypocalcemic vitamin D-resistant rickets (HVDRR) is a hereditary disorder of vitamin D action characterized by hypocalcemia, severe rickets and in many cases alopecia.” 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 2 species entries marked as a defect.

  2. Human disease

    Reached

    2 Mondo diseases.

  3. Human gene

    Reached

    1 human gene.

  4. Target evidence

    Reached

    1 Open Targets association, with a best score of 0.82.

  5. Drugs

    Reached

    18 ChEMBL drugs, 9 approved. None has been tested for this disease.

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:001431-9615 Yes
domestic cat Felis catus OMIA:001431-9685 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 VDR vitamin D (1,25- dihydroxyvitamin D3) receptor NCBI Gene 486588 VDR Ensembl one to one
domestic cat VDR vitamin D (1,25- dihydroxyvitamin D3) receptor NCBI Gene 100316614 VDR Ensembl one to one

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.

The two routes found different diseases. OMIA's own link is broader: its disease is a parent of one the OMIM numbers found.

Mondo disease Name Found by
MONDO:0019642 vitamin D-dependent rickets, type 2 Hypocalcemic vitamin D-resistant rickets (HVDRR) is a hereditary disorder of vitamin D action characterized by hypocalcemia, severe rickets and in many cases alopecia. OMIA's own Mondo link
MONDO:0010186 vitamin D-dependent rickets, type 2A Rickets caused by a defect in the VDR gene, encoding the vitamin D receptor. This form of rickets is characterized by hypocalcemia, elevated 1,25-dihydroxyvitamin D (calcitriol) concentrations and may also manifest with alopecia. OMIA's OMIM numbers

Target evidence

Each Open Targets association between one of the group's human genes and one of its human diseases, with its overall score and the score for each kind of evidence.
