The molecular characterization of the 700 samples which are estimated to pick up during the project will consist of massive sequencing of genes recurrently mutated in AML (ASXL1, had, CBL, CEBPA, DNMT3A, EZH2, FLT3, GATA2, IDH1, IDH2, JAK2, KIT, KRAS, MPL, MLL, NPM1, NRAS, PTPN11, RUNX1, SETBP1, SF3B1, SRSF2, TET2, TP53, U2AF1, WT1). Found mutations will be collated in the different databases of somatic variations to establish which of them could be classified as a driver or passenger.
