Three of five (60%) follicular thyroid adenomas and 1 of 7 (14%) follicular thyroid carcinomas, with the PAX8/PPARgamma fusion gene, were aneuploid.     ///    "RAS mutations and PAX8/PPARgamma fusion gene were investigated in 101 and 87 of these samples, respectively. "    ///    None of the tumours with RAS mutations expressed the PAX8/PPARgamma fusion gene.     ///    "The aim of our study was to investigate the correlation between aneuploidy, RAS mutations and PAX8/PPARgamma gene rearrangement in thyroid follicular tumours.
