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 DYSMORPHIC FACIES AND ISCHIOPUBIC HYPOPLASIA
This disease is an autosomal recessive disorder characterized by dysmorphic facies, ischiopubic hypoplasia, and moderate to severe global developmental delay. Affected individuals show episodic regression during periods of stress, including seizures or infection. Brain imaging shows diminished white matter volume, enlarged ventricles, and thin corpus callosum.
