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.
Term:
NEURODEVELOPMENTAL DISORDER WITH OR WITHOUT EARLY-ONSET GENERALIZED EPILEPSY
A disease characterized by global developmental delay apparent from infancy or early childhood. Affected individuals have variably impaired intellectual development, speech delay, and behavioral abnormalities. Brain imaging is essentially normal and there are no significant accompanying neurologic or systemic abnormalities.
