NTRK1 (neurotrophic tyrosine kinase, receptor, type 1) encodes the high affinity nerve growth factor receptor protein. NTRK1 fusions have been observed in colorectal cancer (PMID: 2869410), papillary thyroid cancer (PMID: 19883730), lung cancer (PMID: 24162815), glioblastoma (PMID: 19883730; PMID: 24647444), and cholangiocarcinoma (PMID: 24563076). NTRK1 fusions trigger constitutive TRKA kinase activity (PMID: 24162815), which activates cell growth and differentiation pathways (PMID: 12652644).

NTRK1 is altered in 2.21% of all cancers with lung adenocarcinoma, colon adenocarcinoma, breast invasive ductal carcinoma, cutaneous melanoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

The most common alterations in NTRK1 are NTRK1 Mutation (2.09%), NTRK1 Amplification (0.43%), NTRK1 R214W (0.03%), NTRK1 R157H (0.02%), and NTRK1 T434M (0.02%) [3].
