Résumé : In this paper, we address the problem of identifying polymorphisms in RNA-seq data when no reference genome is available, without performing an assembly of the transcripts. Based on the fundamental idea that each polymor- phism will correspond to a recognisable pattern in a De Bruijn graph constructed from the RNA-seq reads, we propose a general model for all polymorphisms in such graphs. We then introduce an exact algorithm to extract alternative splic- ing events and show that it enables to identify more correct events than current transcriptome assemblers. Additionally, when we applied our method on a 71M reads dataset from human, we were able to identify 3884 events, out of which 57% are not present in the annotations, which con rms recent estimates show- ing that the complexity of alternative splicing has been largely underestimated so far.
