 Myxoid/round-cell liposarcoma (MLS/RCLS) is characterized by either the fusion gene FUS-DDIT3 or the less commonly occurring EWSR1-DDIT3 and most cases carry few or no additional cytogenetic changes.     ///    Transfection experiments showed that the FUS-DDIT3 fusion protein had no effects on irradiation induced TP53 responses.
