JAZF1/SUZ12 gene fusion in endometrial stromal sarcomas.    ///    In combination with the recently described YWHAE/FAM22 gene fusion the JAZF1/SUZ12 fusion could be used to differentiate between LG-ESS and HG-ESS.     ///    JAZF1/SUZ12 gene fusion in endometrial stromal sarcomas..     ///    To date the JAZF1/SUZ12 gene fusion is by far the most frequent and seems to be the cytogenetic hallmark of ESN and LG-ESS.     ///    The frequency of JAZF1/SUZ12 appearance varies between classic ESS and different morphologic variants.
