Molecular analysis of the JAZF1-JJAZ1 gene fusion by RT-PCR and fluorescence in situ hybridization in endometrial stromal neoplasms..     ///    "Our data suggest that the JAZF1-JJAZ1 fusion is a frequent, although nonuniform, feature of endometrial stromal neoplasia, irrespective of benign versus malignant classification and smooth muscle differentiation. "    ///    "Overall, evidence for the JAZF1-JJAZ1 fusion was found in 60% of endometrial stromal neoplasms analyzed (8/16 ESS and 4/4 stromal nodules).
