However, our PCA showed that EWSR1-NFATc2-translocated sarcomas are clearly distinct from EWSR1-ETS-translocated Ewing sarcomas, and confirm that EWSR1-NFATc2-translocated sarcomas also do not show any transcriptomic similarity with neither CIC-DUX4- nor BCOR-CCNB3-translocated sarcomas (Supplementary Figure 1). This evidence concerns the gene CIC and Ewing sarcoma.
