 Extraskeletal myxoid chondrosarcoma (EMC) is a soft-tissue neoplasm cytogenetically characterized by the translocations t(9;22)(q22;q11-12) or t(9;17)(q22;q11), generating EWS/CHN or RBP56/CHN fusion genes, respectively.     ///    Molecular genetic characterization of the EWS/CHN and RBP56/CHN fusion genes in extraskeletal myxoid chondrosarcoma..     ///    Fifteen cases had an EWS/CHN fusion transcript and three had an RBP56/CHN transcript.     ///    "In all tumors with RBP56/CHN fusion, exon 6 of RBP56 was fused to exon 3 of CHN. "    ///    "Repetitive elements such as Alu and LINE sequences seem to have limited, if any, importance in the genesis of EWS/CHN and RBP56/CHN chimeras. "
