Neurotrophic tyrosine kinase, receptor, type 2 (NTRK2) is a gene that encodes a protein in the neurotrophic tyrosine receptor kinase (NTRK) family that participates in the MAP kinase signaling pathway. Fusions, missense, nonsense, and silent mutations are observed in cancers such as intestinal cancer, skin cancer, and stomach cancer.

NTRK2 is altered in 1.27% of all cancers with lung adenocarcinoma, colon adenocarcinoma, cutaneous melanoma, endometrial endometrioid adenocarcinoma, and bladder urothelial carcinoma having the greatest prevalence of alterations [3].
