EZH2 and myeloproliferative disorder: As a limit of our work, we did not evaluate the numerous non-driver somatic mutations affecting the genes responsible for various cellular processes identified in MPN (DNA methylation: TET2, DNMT3A, IDH1-IDH2; chromatin spliceosome: ASXL1, EZH2, SF3B1, SRSF2, U2AF1, ZRSF2; and others, such as TP53) [35].
