CRLF2 and acute lymphoblastic leukemia: Genomic profiling study on 154 B-ALL cases revealed most common rearrangements of kinase and cytokine receptor genes involving JAK2, ABL1 (with partners other than BCR), and other genes controlling tyrosine kinases including ABL2, CRLF2, CSF1R, EPOR, NTRK3, PDGFRB, PTK2B, TSLP, or TYK2, and gene mutations involving FLT3, IL7R, or SH2B3 [46].
