There was no difference in the expression of the control genes HMGN2 (p = 0.7881) or JAK2 (p = 0.1171) between the cohort of ALL patients or specifically between P2RY8::CRLF2 and BCR::ABL1+ patients (Figures 1C, D, Supplementary Figure S1). This evidence concerns the gene CRLF2 and acute lymphoblastic leukemia.
