A variant of the SYT-SSX2 fusion gene in a case of synovial sarcoma..     ///    "Here we report a case of synovial sarcoma with a novel form of the SYT-SSX2 fusion transcript, in which 75 bases were inserted at the common fusion junction. "    ///    "The structure of SYT-SSX2 suggests that the fusion transcript in this case was created using a cryptic splicing acceptor site 15 bases upstream of the genomic fusion point, incorporating intronic sequences in mature mRNA. "    ///    "Reexamination of two variant SYT-SSX2 genes reported previously revealed that unknown sequences inserted at the common junction points were derived from intron sequences, as in the present case..
