Likewise, BCL‐2 median fluorescence intensity (MFI) was significantly higher in BCP‐ALL (median 190, range 35–397) than in T‐ALL (62, range 23–109, P = 0·02) and >2‐fold higher than normal cells (81, range 75–111, P = 0·09, Fig 2B). The gene discussed is BCL2; the disease is acute lymphoblastic leukemia.
