Abstract

PAX5 rearrangements resulting in the expression of fusion transcripts account for 2-3% of childhood B-cell precursor acute lymphoblastic leukemia. Most PAX5 fusions are rare and many of them have only been described in a couple of, or even only in single, cases. We have identified the third case with a PAX5-AUTS2 fusion, which results from unbalanced t(7;9)(q11.2;p13.2) rearrangements. Our findings substantiate that PAX5-AUTS2 is a recurrent fusion gene in pediatric B-cell precursor acute lymphoblastic leukemia, and we summarize the clinical characteristics of such patients.
