The invention provides to NTRK ('Neurotrophic Tyrosine Receptor Kinase) gene fusions, NTRK. fosion proteins, and fragments of those genes and polypeptides. The invention further provides methods of diagnosing and treating diseases or disorders associated with NTRK fusions, such as conditions mediated by aberrant NTRK expression or activity, or overexpression of NTRK.
