Recently, several studies have revealed a recurrent t(7;17) translocation resulting in a JAZF1-JJAZ1 gene fusion in over 60% of EST and its variants, including 2 out of 4 endometrial stromal tumors with sex cord-like elements (ESTSCLE).     ///    "We examined UTROSCTs for evidence of the JAZF1-JJAZ1 gene fusion by fluorescence in situ hybridization and by reverse transcriptase polymerase chain reaction in 24 and 20 cases, respectively. "    ///    The JAZF1-JJAZ1 gene fusion was not identified in any tumor by either method.     ///    Uterine tumors resembling ovarian sex cord tumors (UTROSCT) lack the JAZF1-JJAZ1 translocation frequently seen in endometrial stromal tumors..
