    Abstract

    Activating tyrosine kinase mutations or cytokine receptor signalling alterations have attracted attention as therapeutic targets for high-risk paediatric acute lymphoblastic leukaemia (ALL). We identified two novel kinase fusions, OFD1-JAK2 and NCOR1-LYN, in paediatric ALL patients with IKZF1 deletion, by mRNA sequencing. The patient with CSF2RA-CRLF2 also harboured IGH-EPOR. All these patients had high-risk features, such as high initial white blood cell counts and initial poor response to prednisolone. The functional analysis of these novel fusions is on-going to determine whether these genetic alterations can be targeted by drugs.
