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.
A neurological condition that is characterized by uncontrolled rapid irregular movements of the eye (OPSOCLONUS) and the muscle (MYOCLONUS) causing unsteady, trembling gait. It is also known as dancing eyes-dancing feet syndrome and is often associated with neoplasms, viral infections, or autoimmune disorders involving the nervous system.
