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.

Infantile Cataract, Skin Abnormalities, Glutamate Excess, and Impaired Intellectual Development
Aside from the clinical features of infantile cataract, skin abnormalities, and impaired intellectual development, CASGID is characterized by strikingly high intracerebral and urinary glutamate excess with almost undetectable glutamine. A gain-of-function mutation in the glutaminase (GLS) gene was found. GLS loss of function is implicated in a form of neonatal epileptic encephalopathy (EIEE71) and a syndrome of global developmental delay and progressive ataxia (GDPAG). (OMIM)
