Neurotrophic tyrosine kinase, receptor, type 3 (NTRK3) is a gene that encodes a protein that belongs to the neurotrophic tyrosine kinase (NTRK) family. The protein functions in the phosphorylation of members of the MAP kinase pathway, cell differentiation, and the development of proprioceptive neurons. Fusions, missense mutations, nonsense mutations, silent mutations, and frameshift deletions are observed in cancers such as intestinal cancer, lung cancer, and skin cancer.

NTRK3 is altered in 2.41% of all cancers with lung adenocarcinoma, colon adenocarcinoma, cutaneous melanoma, squamous cell lung carcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

The most common alterations in NTRK3 are NTRK3 Mutation (2.61%), NTRK3 Amplification (0.10%), NTRK3 Loss (0.04%), NTRK3 K746T (0.02%), and NTRK3 R306H (0.02%) [3].
