Novel formation and amplification of the PAX7-FKHR fusion gene in a case of alveolar rhabdomyosarcoma..     ///    "Comparative genomic hybridization revealed amplification at 13q14 and 1p36, suggesting amplification of the PAX7-FKHR fusion gene in two cases of alveolar rhabdomyosarcoma. "    ///    "Chromatin release studies suggested that the amplified sequences correlated with amplification of the PAX7-FKHR fusion gene which resulted from the insertion of PAX7 sequences into the first intron of FKHR gene, in keeping with the absence of cytogenetic evidence for derivative chromosomes.. "    ///    A PAX7-FKHR fusion transcript was demonstrated in both cases by reverse transcription-polymerase chain reaction followed by sequence analysis.
