TFG is a protein regulating secretion in the ER‐Golgi intermediate compartment (ERGIC) (Hanna et al., 2017; Johnson et al., 2015), and oncogenic fusions of TFG with Trk receptors are involved in thyroid cancer (Greco et al., ,1992, 1998; Roccato et al., 2003). Here, TFG is linked to thyroid cancer.
