In order to prioritize gene fusion candidates with the most read support, we selected candidates with a minimum PEFS of 5 for further investigation. A total of 12 gene fusion candidates with a PEFS >= 5 were identified based on discordantly aligned paired reads. Of these, four candidates (33%) were further found to have supporting reads spanning the exon-exon fusion junction.
