TRK fusions are seen in many solid tumours of children and adults and have targeted drugs.[1]

General

Genes:[2]

  • NTRK1.
  • NTRK2.
  • NTRK3.

Notes:

  • The TRK genes are tropomyosine kinase receptors.
  • Multiple fusion partners for each gene.

Testing:

  • RNA-based next generation sequencing.
  • Immunohistochemistry[3] - limited sensitivity for leiomyosarcoma + others tumours.
  • FISH breakapart probes.
  • DNA NGS[4] - sensitivity low for fusions.

Associations

Classic

Others

Drugs

  • Merestinib.
  • Larotrectinib.[1]
  • Entrectinib.[12]
  • Others.
