Summary: This gene encodes a member of the neurotrophic tyrosine kinase receptor (NTKR) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. The presence of this kinase leads to cell differentiation and may play a role in specifying sensory neuron subtypes. Mutations in this gene have been associated with congenital insensitivity to pain, anhidrosis, self-mutilating behavior, cognitive disability and cancer. Alternate transcriptional splice variants of this gene have been found, but only three have been characterized to date. [provided by RefSeq, Jul 2008]

6 patients with mesenchymal tumors composed of infiltrative fibroblastic/myofibroblastic tumor cells were studied. Using next-generation DNA sequencing, TMP3-NTRK1 fusions were identified in 4 cases, an LMNA-NTRK1 fusion in one case, and a variant EML4-NTRK3 fusion in one case.

High expression of NTRK1 is closely associated with favorable risk factors and outcomes of patients with neuroblastoma (NB). The transcription of variants 1/2 is regulated by the NTRK1 P1 promoter region which is epigenetically regulated by EZH2- related histone modifications. Also, NTRK1 contributes to EZH2-regulated NB cell differentiation.
