These data are consistent with Wang et al. [17], who couldn’t confirm any significant association between TET1 overexpression and patients’ ages or FLT3 mutation, however, they found that the cytogenetically normal AML patients with high TET1 expression showed a higher frequency of NPM1 mutations and FAB M0/1 morphology, while there was no significant association between TET1 expression and TLC, PB nor BM blasts. The gene discussed is NPM1; the disease is acute myeloid leukemia.
