 Extraskeletal myxoid chondrosarcoma is characterized by the reciprocal chromosomal translocation t(9;22) and the resultant fused gene EWS RNA-binding protein 1 and nuclear receptor subfamily 4, group A, member 3 (EWSR1-NR4A3).     ///    "The samples from 42 patients with extraskeletal myxoid chondrosarcoma were examined for the presence of EWSR1-NR4A3, TAF15-NR4A3, TCF12-NR4A3, and TFG-NR4A3 fusion transcripts by using RT-PCR. "    ///    "Of the 34 samples evaluable for fusion transcripts, 23 yielded positive results for EWSR1-NR4A3, 10 for TAF15-NR4A3, and 1 for TCF12-NR4A3.
