Eight common translocations and rearrangements, including ETV6-RUNX1, TCF3-PBX1, BCR-ABL1, ETV6, TCF3, MLL, IGH@, and PAX5, were tested for using dual-color DNA probes.     ///    ETV6-RUNX1 was the most frequent translocation detected in 11 children (34.4%).     ///    ETV6-RUNX1 fusion and ETV6 split-apart rearrangements were not visible by cytogenetics.     ///    All patients with the ETV6-RUNX1 fusion were also identified by split signals for ETV6.
