In addition to the positive correlation between PLCγ2 and CXCR4 observed in MILE leukemia cohort35 (Supplementary Fig. 14c, Pearson’s r = 0.529, p = 1.11E-139), these two genes were also positively correlated in the DLBCL dataset39 (Supplementary Fig. 14d, Pearson’s r = 0.51, p = 0.00027). This evidence concerns the gene PLCG2 and leukemia.
