KEGG Get Disease Genes

Get all human genes linked to a KEGG disease. Returns KEGG gene IDs (hsa:XXXXX format) for genes associated with the disease through mutations, gene fusions, or other mechanisms. Example: H00001 (B-cell ALL) returns hsa:25 (ABL1), hsa:4297 (KMT2A), hsa:4299 (AFF1), etc. Useful for building disease-gene association networks. Optionally specify a different organism.
