EZH2 and chronic myelogenous leukemia, BCR-ABL1 positive: Furthermore, it has been reported in chronic myeloid leukemia that the inclusion of a sequence between exons 8 and 9 of EZH2 gives rise to a premature stop codon with prediction of nonse-mediated decay (NMD) [60]; therefore, we cannot exclude the possibility that this same process occurs with the transcripts evidenced here.
