| Driver Gene | Fusion(s) and Common Partner Genes | Molecular Pathogenesis | Typical Chromosomal Alteration(s) | Prevalence -Common >20%, Recurrent 5-20% or Rare <5% (Disease) | Diagnostic, Prognostic, and Therapeutic Significance - D, P, T | Established Clinical Significance Per Guidelines - Yes or No (Source) | Clinical Relevance Details/Other Notes |
|---|---|---|---|---|---|---|---|
| NTRK3 | ETV6::NTRK3[1] | Fusion results in constitutive activation of NTRK3 tyrosine kinase | t(12;15)(p13;q25) | Common | D, P, T | The ETV6::NTRK3 fusion is diagnostic of secretory carcinoma in the appropriate morphologic and clinical context.[2][3][4] This fusion is responsive to TRK inhibitor therapies such as larotrectinib abd entrectinib. | |
