Fusion gene count and its fold expression relative to nearest control locus.

The genes involved in the fusions are shown; for Klc1 and Arhgef10 the different fusion events are shown independently. Average read counts identified by RNA-seq in each of the 3 independent replicates from either saline or cocaine-treated animals is presented. The expression level of the fusion relative to the nearest control locus (same exon) for saline- and cocaine-exposed animals, respectively, was estimated by qRT-PCR using primers that amplified the repeat-exon junction or the junction between the same exon with the nearest canonical adjacent locus (exon). For more details see Methods. Average fold-change between saline- and cocaine- treated samples, and total standard error are shown; NA = not analyzed. In italic and bold are the 3 genes that are expressed at similar or higher levels than the non-fusion counterpart. Last column represents the results as the ratio of non-fusion over fusion gene expression; i.e. for every 1 transcript of non-fusion Atp2b1 there are 40 transcripts expressing the fusion isoform.
