HS-SY-3 cells were shown to harbor the pathognomonic t(X;18)(p11.2;q11.2) translocation by chromosome analysis but not to exhibit the classical hybrid SYT/SSX transcripts induced by this translocation, using RT-PCR.     ///    " Recent cytogenetical and molecular studies have indicated that synovial sarcoma harbors a t(X;18)(p11.2;q11.2) translocation, resulting in the formation of a hybrid SYT/SSX (SSX1 or SSX2) gene. "    ///    The HS-SY-3 cells should be useful for future functional studies of the SYT/SSX chimeric gene..
