Mutation status of refractory to imatinib patients with chronic myeloid leukemia
Mutation status of 36 chronic myeloid leukemia (CML) patients in chronic phase with primary and secondary imatinib resistance was analyzed. BCR-ABL mutations identified by direct DNA sequencing. BCR-ABL kinase domain mutations were detected in 30.5 % (11 of 36) of those patients. Most of identified...

BCR-ABL mutations identified by direct DNA sequencing. BCR-ABL kinase domain mutations were detected in 30.5 % (11 of 36) of those patients. Most of identified mutations were missense mutations: Q252H, M244V, G250E, Y253F/H, E255K/V, T315I, M351T, F359V, F359C, F486S.
