Novel molecular mechanisms of FLT3 deregulation: from the acute myeloid leukemia experience to therapeutic insights in acute lymphoblastic leukemia.

ABSTRACT: Fms-like tyrosine kinase 3 (FLT3), a class III receptor tyrosine kinase essential for hematopoiesis, is a well-established oncogenic driver in acute myeloid leukemia (AML). Canonical internal tandem duplications (ITD) and tyrosine kinase domain (TKD) mutations inform prognosis and guide targeted therapy. Recent evidence highlights FLT3 as a critical oncogenic hub in acute lymphoblastic leukemia (ALL), where its alterations extend beyond ITD/TKD mutations to include non-canonical mutations with only partially explored functional implications. Moreover, recently discovered regulatory mechanisms, mostly acting on the FLT3 locus, drive FLT3 overexpression in ALL, including transcriptional regulation by rearranged ZNF384, epigenetic modifications, novel circular-RNA URAD::FLT3 fusions, and 13q1
