[Detection of ASPL-TFE3 fusion gene by reverse transcriptase polymerase chain reaction in paraffin-embedded tumor tissues of alveolar soft part sarcoma]..     ///    ASPL-TFE3 fusion transcripts were analyzed in all samples by reverse transcriptase-polymerase chain reaction (RT-PCR).     ///    ASPL-TFE3 fusion transcripts were detected in 6 of the 8 ASPS cases (4 being type 2 and 2 being type 1).     ///    The expression of ASPL-TFE3 fusion transcripts in paraffin-embedded tumor tissues can serve as an useful molecular marker in the diagnosis of ASPS.     ///    The remaining 2 cases were negative for both beta-actin and ASPL-TFE3.     ///    No ASPL-TFE3 mRNA expression was detected in all the controls.
