Abnormal signal patterns were detected in 7% (80/1,087 cases), including 10% (9/94 cases) of ARMS (FOXO1) (Figure 2), 1% (1/61 cases) of CCS (EWSR1) (Figure 6), 6% (29/497 cases) of Ewing sarcoma/round cell sarcoma with EWSR1-non-ETS fusions (EWSR1) (Figures 3, 5, respectively), 32% (6/19 cases) of LGFMS (FUS), 9% (18/209 cases) of NF (USP6) and 8% (17/207 cases) of SS (SS18) (Figure 4).
