RACE results for case 5 indicating the different
HSG2-ETV6 andETV6-HSG2 fusions. The 5′- and 3′-RACE, performed on cDNA obtained from case 5, revealed the existence of 3 differentHSG2-ETV6 fusion transcripts and an ETV6-HSG2fusion transcript. Exon 2 of ETV6 and exon k ofHSG2 are present in both types of fusions, which can only be explained by a duplication event associated with the translocation. Exon k of HSG2 is underlined; sequences from ETV6are in italics; stop codons are in bold.
