| name | t(11;22)(q24;q12.2)(FLI1,EWSR1) and t(21;22)(q22.3;q12.2)(ERG,EWSR1) fusion transcript in Blood or Tissue by Molecular genetics method | ||
| description | Rearrangements of the EWSR1 gene at 22q12 with FLI1 at 11q24 or ERG at 21q22 collectively occur in about 95% of Ewing sarcoma (EWS) and primitive neuroectodermal tumors (PNET), both types of small round-cell tumors. The fusion transcripts can be detected by various methods, including reverse transcriptase PCR and FISH. A positive result is consistent with a diagnosis of EWS/PNET. A negative result does not rule out the presence of fusion transcripts that may be present, but below the detection limit of an assay. | ||
