As expected, none of the five myxoid liposarcomas, which all had a t(12;16) resulting in a FUS-DDIT3 fusion gene (data not shown), expressed HMGA2. Similarly, most hibernomas and spindle cell lipomas, which at the chromosome level typically show translocations affecting chromosome band 11q13 and deletions of 13q, respectively, did not show any deregulation of HMGA2. However, one case each demonstrated moderate expression of the full-length gene (hibernoma, log10 ratio exons 1–2, 1.60) or only of the amino-terminal part (spindle cell lipoma, log10 ratio exons 1–2, 1.76). This evidence concerns the gene FUS and myxoid liposarcoma.
