As expression data in chronic myeloid leukaemia (CML) or acute lymphoblastic leukaemia (ALL) are not covered by the SurvExpress database, we switched to a different platform (Genevestigator; https://genevestigator.com/gv/; Hruz et al, 2008) which provides data of BCR/ABL1‐driven diseases. The gene discussed is BCR; the disease is acute lymphoblastic leukemia.
