Disease associations assigned to cell lines by the National Cancer Institute (NCI / NCIt) and the Orphanet portal for rare diseases and orphan drugs (Orphanet / ORDO) were imported from Cellosaurus. The Disease Ontology (DO) terms have been associated with the corresponding cell line records in RGD. These disease associations reflect the use of the cell lines as models for a disease and/or the clinical diagnosis of the patient from whom tissue was taken to establish the cell line. The associations are imported without further review and have been assigned the evidence code "IEA" to reflect this.
