Fused in Sarcoma/Translocated in Liposarcoma (FUS/TLS) belongs to the FET (FUS- EWSR1, TAF15) family protein and was described for the first time in myxoid liposarcoma as an oncogenic fusion of the dominant negative transcription factor gene CHOP with the gene FUS [1,2]. This evidence concerns the gene FUS and myxoid liposarcoma.
