MED12 and undifferentiated pleomorphic sarcoma: Using RNA-seq and other methodologies, analysis of 84 soft tissue sarcomas revealed that a significant subset of low-grade undifferentiated pleomorphic sarcoma (UPS) showed a gene fusion of PRDM10 either with MED12 or CITED2, suggesting that these rearrangements were specific for this less aggressive UPS subset [161].
