t(2;14)(p13;q32): a recurring abnormality in lymphocytic leukemia. A Pediatric Oncology Group study.

Chromosome banding studies of 1,411 children with newly diagnosed acute lymphocytic leukemia (ALL) identified two patients with the t(2;14)(p13;q32) chromosome abnormality and a third patient with a complex three-way translocation involving the same breakpoints on chromosomes 2 and 14 but also involving chromosome 12 at band q11. The three cases demonstrated variability of immunophenotypes: one was a T-cell ALL, and two were early pre-B ALLs. All three patients achieved complete remissions and have remained in remission for 14-19 months.
