Abstract
The search for tumour-specific markers is one of the chief goals in cancer biology. We show that the translocation t(12;16)(q13:p11) in malignant myxoid liposarcoma can be a fusion of the CHOP dominant negative transcription factor gene with a novel gene, FUS, which can result in fusion of the FUS glycine-rich protein with the whole CHOP coding region. The data support the concept that protein fusion may commonly occur in solid tumours resulting in tumour-specific markers of potential clinical importance. The data also indicate the importance of transcription disruption in the pathogenesis of solid tumours.
