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.
This disease is an X-linked recessive disorder characterized by the onset of inflammatory symptoms in the first decade of life in male patients. The disorder results from a defect in ELF4, which normally acts as a negative regulator of inflammatory disease.
