RUNX1 and myelodysplastic syndrome: Our data revealed that TET1/2 (52/91, 57.1%) was the most prevalent co‐mutation in NPM1mut AML patients, followed by IDH1/2 (36/91, 39.6%), DNMT3A (35/91, 38.5%), myelodysplastic syndrome related genes (MDS‐related genes) (ASXL1, BCOR, EZH2, RUNX1, SF3B1, SRSF2, STAG2, U2AF1 and ZRSR2 genes) (35/91, 38.5%), FLT3‐TKD (27/91, 29.7%) and GATA2 (13/91, 14.3%) mutations.
