In KMT2A/MLL-R+ infant ALL cells, FLT3_206674_at was the most significantly upregulated probeset (Fold Change = 11.23; < 10-8) followed by BLK_206255_at (Fold Change = 3.98; < 10-8) when compared to infant ALL cells with germline/wildtype KMT2A/MLL gene [Figure 1; Supplementary Table 4]. The gene discussed is KMT2A; the disease is acute lymphoblastic leukemia.
