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 congenital nervous system abnormality characterized by migration of neurons to ectopic locations in the brain where the neurons form areas that appear as band-like clusters of white tissue underneath the gray tissue of the cerebral cortex. (DO)
