Zusammenfassung
Overexpression of the cytokine receptor-like factor 2 (CRLF2) gene in acute lymphoblastic leukemia (ALL) is caused by different aberrations like a deletion juxtaposing CRLF2 with the P2RY8 promoter, by a translocation involving the immunoglobulin heavy chain locus (IGH@), by supernumerary copies of the CRLF2 locus or by not yet identified causes. Several retrospective studies showed that only the presence of the P2RY8-CRLF2 rearrangement is associated with a high incidence of relapse in CRLF2-overexpressing precursor B-cell ALL (pB-ALL) in children; however, prospectively assessed data are missing. We therefore…
