Neurotrophic tyrosine kinase ( NTRK) is the name of the family of three genes encoding tropmomyosin receptor kinases ( Trk) A, B, and C. Tropomyosin receptor kinases belong to a larger group of receptor tyrosine kinases. Receptor tyrosine kinases exist as monomers in the absence of extracellular ligands, usually growth factors.

In those days, fusion proteins were called chimeras, after a Greek mythological monster. The syntax in most common usage The NTRK NGS Fusion Panel is an RNA-based next-generation sequencing panel that detects translocations and fusions of the Neurotrophic Tropomyosin-Related Kinase (NTRK) genes NTRK1, NTRK2, and NTRK3 with known and novel fusion partners. Point mutations in select exons of these three genes are also detected. What are NTRK (1/2/3)?

This leads to deregulated neural development – neuron growth, differentiation, proliferation, and apoptosis all fall into disarray, and important synaptic pathways are compromised.

NTRK : Identifying solid tumors that may respond to targeted therapies by simultaneously assessing for rearrangements involving targeted regions of the NTRK1, NTRK2, and NTRK3 genes resulting in fusion transcripts This test is not useful for hematologic malignancies.

NTRK gene fusions result from intra-chromosomal or inter-chromosomal rearrangements that juxtapose the 3’ region of the NTRK gene with the 5’ sequence of a fusion partner gene expressed by the tumour cell progenitor .2 The NTRK gene fusion transcript encodes a protein composed of the N-terminus of the fusion partner with the TRK partner tyrosine kinase domain.2 In most characterised

In solid tumors, the presence of an NTRK gene fusion is a biomarker for response to tropomyosin receptor kinase (TRK) inhibitor therapy. Similar to other NTRK receptors and receptor tyrosine kinases in general, ligand binding induces receptor dimerization followed by trans-autophosphorylation on conserved tyrosine in the intracellular (cytoplasmic) domain of the receptor. These conserved tyrosine serve as docking sites for adaptor proteins that trigger downstream signaling cascades.
