Fig. 2: Geneplots for patients treated with JAKi organized by pattern of JAKi failure (x-axis) and mutation category (y-axis).

a Baseline mutations present prior to start of JAKi therapy, with no difference in number or genes mutated between pattern of failure groups. b Geneplot demonstrating n = 55 patients with paired mutation analysis arranged by pattern of failure (n = 49) or ongoing response to JAKi (n = 6). Emergent mutations were more frequently observed in patients with JAKi failure due to AP/BP (n = 7/10) than failure due to cytopenia (n = 1/10, P = 0.006).
