In Braun et al.'s study, mutations in leukemia-related genes including TET2 and ASXL1 did not predict positive response to HMT in chronic myelomonocytic leukemia (CMML), one of the myelodysplastic/myeloproliferative disorders [15]. The gene discussed is ASXL1; the disease is chronic myelomonocytic leukemia.
