A specific chromosomal translocation, t(X;17)(p11.2;q25), results in the ASPL-TFE3 fusion gene: it is detectable using reverse-transcription polymerase chain reaction (RT-PCR) in frozen tumor tissues of ASPS.     ///    "Here, we report the first systematic study applying TFE3 immunoassay and ASPL-TFE3 fusion transcript detection to archival paraffin-embedded tissues in a large Chinese ASPS patient population. "    ///    No expression of ASPL-TFE3 fusion transcripts was detectable in all 38 control tumors.     ///    Alveolar soft part sarcoma: a bimarker diagnostic strategy using TFE3 immunoassay and ASPL-TFE3 fusion transcripts in paraffin-embedded tumor tissues..     ///    "Of these 11, 7 were type 1 ASPL-TFE3 and 4 were type 2 ASPL-TFE3, including the tumor located in the renal hilum. "    ///    "Our results demonstrate that the ""bimarker strategy,"" a combination of TFE3 immunostaining and ASPL-TFE3 chimeric transcript detection, might have sufficient sensitivity and specificity in diagnosing most of the ASPSs. "    ///    "Using a strategy of RT-PCR, followed by a nested PCR with a different primer set, we were able to detect the expression of the chimeric ASPL-TFE3 mRNA in 11 of the 16 ASPS tumors. "
