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:
Congenital Hypotonia, Epilepsy, Developmental Delay, and Digital Anomalies
A syndromic neurodevelopmental disorder characterized by severe global developmental delay, impaired intellectual development with poor or absent language, significant motor disability with inability to walk, dysmorphic facial features, skeletal anomalies, and variable congenital anomalies.
