In all the B-ALL patients (BG_41985, BG_11584, BG_41182, BG_42309, and BG_5038), we identified a single variant involving one single gene (FLT3, TP53, JAK2, CREBBP, and PAX5, respectively), while only one T-ALL patient (BG_21292) presented a single gene involved. This evidence concerns the gene JAK2 and acute lymphoblastic leukemia.
