We have identified the fusion gene SNX2-ABL1 in a pediatric case of acute lymphoblastic leukemia (ALL), which has only once previously been reported in an adult patient.     ///    Treatment using tyrosine kinase inhibitors requires further investigation to optimize the genotype-based treatment stratification for patients with SNX2-ABL1 fusion.     ///    ALL cells carrying a SNX2-ABL1 fusion exhibited a BCR-ABL1+ ALL-like gene expression profile.     ///    Poor responses to tyrosine kinase inhibitors in a child with precursor B-cell acute lymphoblastic leukemia with SNX2-ABL1 chimeric transcript..
