Zusammenfassung
Background: PAX5, a master regulator of B-cell development, was shown to fuse to AUTS2, C20orf112, ELN, ETV6, FOXP1, and ZNF521 in B-cell precursor acute lymphoblastic leukemia (BCP-ALL). To determine the overall incidence and the whole spectrum of PAX5 fusion partners in childhood ALL a population-based FISH screening study was performed. Patients: 446 children with de novo ALL registered in the Austrian ALL-BFM-2000 and Interfant-99 studies were analyzed. Methods: A dual-color split-apart FISH assay with BAC clones flanking PAX5 was employed. Novel fusion partners were identified by FISH, 3' or 5' RACE, and su…
