The PCR amplicons for the primary and recurrent/metastatic tumor samples were identical and also the same size as the BER-DSRCT amplicon, suggesting the fusion in these tumors adjoined exon 7 of EWSR1 to exon 8 of WT1 as previously described for BER-DSRCT [13]. The gene discussed is WT1; the disease is metastatic neoplasm.
