## Abstract ## Background Most alveolar rhabdomyosarcomas (ARMS) have chromosome translocations and resultant gene fusion products. The more common translocation fuses the PAX3 and FKHR genes; patients who have PAX3βFKHRβpositive ARMS have reduced eventβfree survival compared to patients with ARMS
## Abstract We analyzed the expression signatures of 14 tumor biopsies from children affected by alveolar rhabdomyosarcoma (ARMS) to identify genes correlating to biological features of this tumor. Seven of these patients were positive for the __PAX3βFKHR__ fusion gene and 7 were negative. We used
Alveolar rhabdomyosarcomas frequently exhibit specific translocations, resulting in the fusion of the FKHR gene at 13q 14 with either the PAX3 or PAX7 gene at 2q35 and I p36, respectively. Comparative genomic hybridization revealed amplification at 13q14 and lp36, suggesting amplification of the PAX
