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 complex developmental disorder characterized by global developmental delay, variably impaired intellectual development, and craniofacial and structural brain abnormalities. Brain imaging shows crowding of the posterior fossa, including rhombencephalosynapsis (partial or complete loss of the cerebellar vermis with fusion of the cerebellar hemispheres), as well as perisylvian polymicrogyria and cerebellar hypoplasia/dysplasia.
