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.

NEURODEVELOPMENTAL DISORDER WITH SEIZURES AND GINGIVAL OVERGROWTH
This disease is an autosomal recessive disorder with a highly variable phenotype. Most patients develop significant gingival hypertrophy associated with a prominent mandible or cherubism in the first years of life. The disorder appears to comprise a continuum of evolving neurologic manifestations.
