In this study, we examined highly enriched CD34+ cells from patients with BCR-ABL-positve CML in chronic phase or blast crisis for the JAK2 V617F activation mutation by sequencing. The cells examined did not bear the mutation irrespective of the disease stage. This finding suggests that the previously described increase of expression and kinase activity of JAK2 in CML cells does not result from the JAK2 V617F activation mutation and that transformation into blast crisis is not associated with the occurrence of this mutation.
