Fig. 2: Mutational landscape.

Cases of MDS/MPN-U with isolated i(17q) show significantly higher frequency of mutations in SETBP1 and SRSF2 compared to cases of MDS/MPN-U without i(17q). There were no significant differences in mutational frequencies in other genes such as ASXL1 and TET2. TP53 mutations were rare. Cases of MDS/MPN-U with clonal mutations in one of the MPN-associated genes that included JAK2, CALR, and MPL were excluded.
