These groups have been categorized as the round cell sarcomas associated with fusion forming EWSR1 (non-ETS fusions), the CIC (Capicua Transcriptional Repressor) rearrangement associated sarcomas, and BCOR (BCL-6 transcriptional co-repressor) associated sarcomas (Sbaraglia et al., 2021). This evidence concerns the gene CIC and sarcoma.
