A longitudinal study of the JAK2(V617F) mutation in myelofibrosis with myeloid metaplasia: analysis at two time points.
Serial analysis for the activating JAK2(V617F) mutation performed in 44 patients with myelofibrosis with myeloid metaplasia showed no interval change in 88% (22/25) of patients over a median interval of 18.6 months. The increase in JAK2 expression observed in three patients did not correspond to disease progression or leukemic transformation.
