HOXA9

  • HOXA9 is a gene essential to myeloid differentiation that is expressed in PICALM-MLLT10 and MLL-rearranged acute leukemias.

Pathology

- overexpression of HOXA9 in tumors

  • leukemias (#16518848#)

NB: Constitutive activation of tyrosine kinases by mutations or fusions as BCR-ABL1 could be associated with deregulation of transcription factors central to myeloid differentiation (HOXA9 secondary to PICALM-MLLT10).
