From the MinION/PromethION data set of LC2/ad, we successfully identified 12 reads directly overlapping the junction point of the CCDC6-RET fusion gene, which is the most important cancer driver mutation for this cell line (for details of the bioinformatics pipeline, see Methods) (Fig. 2A; Matsubara et al. 2012; Suzuki et al. 2013b). Here, RET is linked to cancer.
