Summary Cure rates of children and adults with acute myeloid leukaemia ( AML ) remain unsatisfactory partly due to chemotherapy resistance. We investigated the genetic basis of AML in 107 primary cases by sequencing 670 genes mutated in haematological malignancies. SETBP 1 , ASXL 1 and RELN mutations were significantly associated with primary chemoresistance. We identified genomic alterations not previously described in AML , together with distinct genes that were significantly overexpressed in therapy‐resistant AML . Defined gene mutations were sufficient to explain primary induction failure in only a minority of cases. Thus, additional genetic or molecular mechanisms must cause primary chemoresistance in paediatric and adult AML .
