By reanalyzing the NKTCL data11, we discovered two previously undetected STAT3 mutations and a JAK2 mutation (p.V617F) in the NKTCL cohort, further expanding the fraction of NKTCL patients with JAK-STAT mutations (Fig. 2a). The gene discussed is STAT3; the disease is extranodal nasal NK/T cell lymphoma.
