Similarly, FLT3 and BLK expression in leukemic cells from adult patients with KMT2A/MLL-R+ ALL were 21.00-fold (P-value < 1 × 10-8) and 21.79-fold (P-value < 1 × 10-8), respectively, higher than in normal hematopoietic cells [Supplementary Figure 3; Supplementary Table 3]. Here, FLT3 is linked to acute lymphoblastic leukemia.
