The cluster 10 molecular subtype is enriched by basal‐like cancer subtype tumors and clinically defined as triple‐negative, highly aggressive, drug resistance, and high‐risk metastasis tumor genes that includes numerous signaling molecules, transcription factors, mitotic, and other cell division genes associated in trans with this deletion event in the basal cancers, including alterations in AURKB, BCL2, BUB1, FOXM1, KIF2C, KIFC1, RAD51AP1, TTK, and UBE2C. The gene discussed is BCL2; the disease is cancer.
