Molecular characterization of an EWSR1-POU5F1 fusion associated with a t(6;22) in an undifferentiated soft tissue sarcoma..     ///    "Evaluation of existing data on the known EWSR1-POU5F1 tumors suggests that the fusion gene functions in a wide variety of cell types and may modify the differentiation state of cells, resulting in susceptibility to tumorigenesis.."    ///    "Evaluation of existing data on the known EWSR1-POU5F1 tumors suggests that the fusion gene functions in a wide variety of cell types and may modify the differentiation state of cells, resulting in susceptibility to tumorigenesis.. "    ///    "This report is novel in that to our knowledge, it is the first complete molecular characterization of an EWSR1-POU5F1 fusion in a soft tissue sarcoma. "    ///    Molecular studies confirmed the presence of an EWSR1-POU5F1 fusion creating a chimeric gene with the N-terminal transcriptional activation domain of EWSR1 and the C-terminal POU DNA binding domain of POU5F1.
