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:
megalencephalic leukoencephalopathy with subcortical cysts
A leukodystorphy characterized by infantile-onset macrocephaly, often with mild neurologic signs at presentation (such as mild motor delay), which worse with time, leading to poor ambulation, falls, ataxia, spasticity, increasing seizures and cognitive decline. (DO)
