Our negative result is similar to Pardanani et al. [27] report that no FLT3 mutations were found in a cohort of patients with chronic myeloid disorders, while being in contrast to Lin's study that FLT3 mutations occur in approximately 10% of Philadelphia (Ph) chromosome-CMPD and CMPD/MDS [5]. Here, FLT3 is linked to myeloproliferative neoplasm.
