NF1 expression analysis in pediatric T-ALL and MLL-rearranged AML.NF1 mRNA expression data relative to GAPDH (%), based upon gene expression array data, which were available for 3 del(17)(q11.2)-positive (patient no. 2736, 2780, and 167) and 7 del(17)(q11.2)-negative patients with leukemia. The horizontal bars represent median relative expression.
