Likewise, in KMT2A/MLL-R+ pediatric ALL cells, FLT3_206674_at was the most significantly upregulated probeset (Fold Change = 8.65; P-value < 1 × 10-8) followed by BLK_206255_at (Fold Change = 3.11; P-value < 10-8) when compared to pediatric ALL cells without KMT2A/MLL rearrangements [Figure 2; Supplementary Table 5]. The gene discussed is KMT2A; the disease is acute lymphoblastic leukemia.
