BCL2, BCLXL, and MCL1 dependencies were defined as indicated in Figure 1B (red, high; orange, intermediate, green, not dependent). Molecular groups were determined either by fluorescence in situ hybridization or by quantitative polymerase chain reaction gene expression of anchorage genes of each molecular subgroup in purified CD138⁺ myeloma cells as defined in supplemental Table 1. Diag, diagnosis; F, female; M, male; NA, data not available; ns, nonsecreting; PC, plasma cells; Rel, relapse.
