FIGURE 2.

Frequency of genomic alterations in adult T‐cell leukemia/lymphoma (ATLL). A, Frequency of somatic mutations across the cohorts. Genes that were recurrently mutated in a previous report (Kataoka et al, Nat Genet 2015) were summarized. *PRKCB, CCR4, VAV1, IRF4, CCR7, HLA‐B, and HNRNPA2B1 were not evaluated in a North American ATLL cohort. **IRF2BP2 was not evaluated in young Japanese and North American ATLL cohorts. B, Frequency of co‐occurrence of CTLA4‐CD28 and ICOS‐CD28 fusions in peripheral T‐cell lymphoma (PTCL) including ATLL
