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:
NEURODEGENERATION WITH DEVELOPMENTAL DELAY, EARLY RESPIRATORY FAILURE, MYOCLONIC SEIZURES, AND BRAIN ABNORMALITIES
This disease is a severe autosomal recessive disorder characterized by onset of symptoms in infancy. Patients present with respiratory failure and require intubation soon after birth. Patients who survive show severe global developmental delay, refractory myoclonic seizures, hyperkinetic movements with exaggerated startle response, and microcephaly with dysmorphic features.
