KEGG analysis indicated that BCL2L11 participated primarily in pathways related to cancer, Epstein–Barr virus infection, FoxO signaling, and apoptosis, and most genes were involved in the MAPK signaling pathway, metabolic pathways, IL-17 signaling pathway, NOD-like receptor signaling pathway, and TNF signaling pathway. The gene discussed is BCL2L11; the disease is cancer.
