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?
Associations
Classic
- Mammary analogue secretory carcinoma (MASC) - ETV6-NTRK3.[4]
- Secretory breast carcinoma - ETV6-NTRK3.[5]
Others
Drugs
- Merestinib.
- Larotrectinib.[1]
- Others.
