Orphanet Rare Disease Ontology 4.0

The Orphanet Rare Disease ontology (ORDO) is 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 derived from the Orphanet database (www.orpha.net ) , a multilingual database dedicated to rare diseases populated from literature and validated by international experts.
