We also observed associations between fusion status and expression level in well-known fusions (Table S3), such as RET–NTRK1 in thyroid cancer, EML4–ALK in lung cancer (Stransky et al., 2014), and DNAJB1–PRKACA in the FLC subtype of liver cancer (Dinh et al., 2017). This evidence concerns the gene RET and lung carcinoma.
