These data are for research purposes only. While the Orphadata data is open to the public,
users seeking information about a personal medical or genetic condition are urged to consult with
a qualified physician for diagnosis and for answers to personal medical questions.
UCSC presents these data for use by qualified professionals, and even such professionals
should use caution in interpreting the significance of information found here. No single data point
should be taken at face value and such data should always be used in conjunction with as much
corroborating data as possible. No treatment protocols should be developed or patient advice given
on the basis of these data without careful consideration of all possible sources of information.
No attempt to identify individual patients should be undertaken. No one is authorized to
attempt to identify patients by any means.
The Orphadata: Aggregated data from Orphanet (Orphanet) track shows genomic positions
of genes and their association to human disorders, related epidemiological data, and phenotypic
annotations. As a consortium of 40 countries throughout the world,
gathers and improves knowledge regarding rare diseases and maintains the Orphanet rare disease
nomenclature (ORPHAcode), essential in improving the visibility of rare diseases in health and
research information systems. The data is updated monthly by Orphanet and updated monthly
on the UCSC Genome Browser.
Mouseover on items shows the gene name, disorder name, modes of inheritance(s) (if available),
and age(s) of onset (if available). Tracks can be filtered according to gene-disorder association
types, modes of inheritance, and ages of onset. Clicking an item from the browser will return
the complete entry, including gene linkouts to Ensembl, OMIM, and HGNC, as well as phenotype information
using HPO (human phenotype ontology) terms.

the Orphadata FAQs.
The raw data can be explored interactively with the Table Browser,
or the Data Integrator.
For automated analysis, the data may be queried from our REST API.
