Nevertheless, we recognize there is at least a possibility that for some of the nine patients with the JAK2 p.V617F mutation in our study, the clonal population in blood due to CHIP may approach 100% and the percentage of hematological cells in the sequenced tumor samples is higher than typical cases, therefore leading to the detection of the JAK2 p.V617F mutation due to infiltrating hematological cells. The gene discussed is STUB1; the disease is neoplasm.
