We uncovered a complex cryptic rearrangement that gives rise to the characteristic SYT-SSX2 fusion gene in a monophasic synovial sarcoma..     ///    Cryptic chromosome rearrangement resulting in SYT-SSX2 fusion gene in a monophasic synovial sarcoma..     ///    "Comparative genomic hybridization detected losses of Xq21qter, 18p, and 18q12qter, indicating that the marker also contained DNA sequences from Xp22q21, and reverse-transcription polymerase chain reaction demonstrated a SYT-SSX2 fusion transcript.
