                    The Orphanet Rare Disease ontology (ORDO) was initially jointly developed by Orphanet and the EBI to provide a structured vocabulary for rare diseases capturing relationships between diseases, genes and other relevant features which
                      will form a useful resource for the computational analysis of rare diseases. It is derived from the Orphanet database
                      www.orpha.net , a multilingual database dedicated to rare diseases populated from literature and validated by international experts. It integrates a nosology (classification of rare diseases), relationships (gene-disease relations,
                      epidemiological data) and connections with other terminologies (MeSH, UMLS, MedDRA), databases (OMIM, UniProtKB, HGNC, ensembl, Reactome, IUPHAR, Genatlas) or classifications (ICD-10).
                    The ontology will be maintained by Orphanet and further populated with new data. Orphanet classifications can be browsed in the OLS view. The Orphanet Rare Disease Ontology is updated every six months and follows the OBO guidelines
                      on deprecation of terms.
