For instance, EZH2 mutations occur in follicular lymphoma (FL) [57,58], germinal center B-cell like (GCB) DLBCLs [59,60,61,62,63], MDS [64], myeloproliferative neoplasms (MPN) [65], and juvenile myelomonocytic leukemia (JMML) [66,67]. This evidence concerns the gene EZH2 and juvenile myelomonocytic leukemia.
