KMT2A and acute lymphoblastic leukemia: Similarly, in KMT2A/MLL-R+ adult ALL cells, FLT3_206674_at was the most significantly upregulated probeset (Fold Change = 5.69; P-value < 10-8) followed by BLK_206255_at (Fold Change = 3.95; P-value < 10-8) when compared to leukemic cells from adult ALL patients without KMT2A/MLL rearrangements [Figure 3; Supplementary Table 6].
