The most frequently mutated genes in these patients were ASXL1, TET2, SRSF2, U2AF1, RUNX1, and TP53. IDH1 and IDH2 genes were mutated in 7% and 10% of cases, respectively and this frequency did not change after progression to AML [62]. The gene discussed is ASXL1; the disease is acute myeloid leukemia.
