RGD uses the Human Disease Ontology (DO, https://disease-ontology.org/) for disease curation across species. RGD automatically downloads each new release of the ontology on a monthly basis. Some additional terms which are required for RGD's curation purposes but are not currently covered in the official version of DO have been added. As corresponding terms are added to DO, these custom terms are retired and the DO terms substituted in existing annotations and subsequently used for curation.
An extrinsic allergic alveolitis that is characterized by a set of symptoms such as headache, fatigue, eye irritation, and breathing difficulties that affect workers in modern airtight office buildings. The disease is caused by indoor pollutants (as formaldehyde fumes, particulate matter, or microorganisms), and the symptoms tend to disappear when affected individuals leave the building. (DO)
