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.
An EWSERI-negative small round cell tumor that is characterized by a recurrent translocation involving the CIC gene on chromosome 19 and either DUX4 gene on chromosome 4 or DUX4L gene on chromosome 10. The translocation results in either CIC-DUX4, t(4;19)(q35;q13) or CIC-DUX4L, t(10;19)(q26;q13) fusions. (DO)
