This screen confirmed that the FYN-TRAF3IP2 fusion is highly recurrent as it was detected (and verified by Sanger sequencing) in 6/37 (3 PTCL-NOS, 3 PTCL-TFH) samples (Supplementary Fig. 1d, e, Supplementary Table 2). The gene discussed is FYN; the disease is mature T-cell and NK-cell non-Hodgkin lymphoma.
