Conversely, several NTRK gene fusions, previously documented in patients with NSCLC, were not found in our NSCLC cohort, including TPM3::NTRK1 [8, 17], SQSTM1 partnered with NTRK1/NTRK2/NTRK3 [20, 28, 37, 38], ETV6-NTRK3 [17], IRF2BP2-NTRK1 [8], EPS15::NTRK1 [37], and CD74-NTRK1 [28]. Here, NTRK2 is linked to non-small cell lung carcinoma.
