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). The gene discussed is NTRK1; the disease is thyroid gland carcinoma.
