Short-read transcriptome sequencing has expanded our knowledge of fusion genes that drive cancer. However, fusion-finding algorithms designed for short reads do not work on data from Oxford Nanopore Technologies. JAFFAL is a new method to identify fusions from long-read transcriptome sequencing. We validated JAFFAL using simulation, patient, and cell line data. By applying JAFFAL, we show that direct RNA sequencing is free from chimeric molecules generated during cDNA library preparation, long reads capture fusion transcript splicing, and fusions can be detected in single cells.
