UniProtRef Search Diseases

Search the UniProt controlled disease vocabulary for disease definitions. Returns disease entries with OMIM, MeSH, MedGen, and SNOMED cross-references plus the number of reviewed proteins associated with each disease. Use this to find UniProt disease IDs (DI-XXXXX) for downstream analysis. Example: searching 'breast cancer' returns DI-03803 (lobular breast cancer), DI-01559 (familial breast-ovarian cancer 1), DI-02603 (familial breast-ovarian cancer 2).
