NTRK1

protein-coding

neurotrophic receptor tyrosine kinase 1, the group of Immunoglobulin like domain containing|Receptor tyrosine kinases

Gene 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]

In the context of congenital insensitivity to pain (CIP), the gene NTRK1 was first discovered in mice, in which homozygous knock-out led to loss of temperature and pain perception, autonomic disturbances such as alacrimation, and severe ulcerations (PMID: 8145823). In patients with the same phenotype, including anosmia, and an autosomal recessive mode of inheritance, NTRK1 was first described in 1996 (PMID: 8696348), followed by the discovery of several missense (e.g. PMID: 11159935​), stop (e.g. PMID: 28328124), frame-shift (e.g. PMID: 28328124​), and splice variants (e.g. PMID: 10330344), all falling into the biallelic loss-of-function cluster. NTRK1 is a nerve growth factor (NGF) receptor and tyrosine kinase. Following internalization, it is involved in several processes, including regulation of inflammatory factor release​ and phagocytosis. One of its substrates is TRPV1, a nonselective cation channel expressed in small nerve endings that is responsible for the perception of heat pain and that can be sensitized by the presence of NGF (PMID: 27732851). Several patient cases and animal models reproduce the highly specific CIP phenotype. In summary, NTRK1 is DEFINITIVELY associated with autosomal recessive congenital insensitivity to pain (CIP). This was repeatedly demonstrated in both research and clinical diagnostic settings, and has been upheld over time.

Manifestation: Allergy/Immunology/Infectious; Dermatologic; Neurologic

Intervention: Allergy/Immunology/Infectious; Dermatologic; Neurologic

Rationale: Individuals may manifest with poor thermoregulation due to anhidrosis, which may result in potentially severe fevers, and awareness can allow measures to help control temperature in order to decrease potential sequelae; Congenital insensitivity to pain can result in injuries, some of which may in theory be preventable with early diagnosis and preventive measures (eg, tooth extraction may be indicated); Recurrent infections have been described, and preventive measures and awareness allowing early diagnosis and aggressive treatmentment of infections may be beneficial

Function
FUNCTION: Receptor tyrosine kinase involved in the development and the maturation of the central and peripheral nervous systems through regulation of proliferation, differentiation and survival of sympathetic and nervous neurons. High affinity receptor for NGF which is its primary ligand (PubMed:1850821, PubMed:1849459, PubMed:1281417, PubMed:8325889, PubMed:15488758, PubMed:17196528, PubMed:27445338). Can also bind and be activated by NTF3/neurotrophin-3. However, NTF3 only supports axonal extension through NTRK1 but has no effect on neuron survival (By similarity). Upon dimeric NGF ligand-binding, undergoes homodimerization, autophosphorylation and activation (PubMed:1281417). Recruits, phosphorylates and/or activates several downstream effectors including SHC1, FRS2, SH2B1, SH2B2 and PLCG1 that regulate distinct overlapping signaling cascades driving cell survival and differentiation. Through SHC1 and FRS2 activates a GRB2-Ras-MAPK cascade that regulates cell differentiation and survival. Through PLCG1 controls NF-Kappa-B activation and the transcription of genes involved in cell survival. Through SHC1 and SH2B1 controls a Ras-PI3 kinase-AKT1 signaling cascade that is also regulating survival. In absence of ligand and activation, may promote cell death, making the survival of neurons dependent on trophic factors. {ECO:0000250|UniProtKB:P35739, ECO:0000250|UniProtKB:Q3UFB7, ECO:0000269|PubMed:11244088, ECO:0000269|PubMed:1281417, ECO:0000269|PubMed:15488758, ECO:0000269|PubMed:17196528, ECO:0000269|PubMed:1849459, ECO:0000269|PubMed:1850821, ECO:0000269|PubMed:27445338, ECO:0000269|PubMed:27676246, ECO:0000269|PubMed:8155326, ECO:0000269|PubMed:8325889}.;
Disease
DISEASE: Congenital insensitivity to pain with anhidrosis (CIPA) [MIM:256800]: Characterized by a congenital insensitivity to pain, anhidrosis (absence of sweating), absence of reaction to noxious stimuli, self-mutilating behavior, and mental retardation. This rare autosomal recessive disorder is also known as congenital sensory neuropathy with anhidrosis or hereditary sensory and autonomic neuropathy type IV or familial dysautonomia type II. {ECO:0000269|PubMed:10090906, ECO:0000269|PubMed:10233776, ECO:0000269|PubMed:10330344, ECO:0000269|PubMed:10567924, ECO:0000269|PubMed:10861667, ECO:0000269|PubMed:10982191, ECO:0000269|PubMed:11159935, ECO:0000269|PubMed:11310631, ECO:0000269|PubMed:18077166, ECO:0000269|PubMed:22302274, ECO:0000269|PubMed:27676246, ECO:0000269|PubMed:28177573, ECO:0000269|PubMed:28328124, ECO:0000269|PubMed:8696348}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Note=Chromosomal aberrations involving NTRK1 are found in papillary thyroid carcinomas (PTCs) (PubMed:2869410, PubMed:7565764, PubMed:1532241). Translocation t(1;3)(q21;q11) with TFG generates the TRKT3 (TRK-T3) transcript by fusing TFG to the 3'-end of NTRK1 (PubMed:7565764). A rearrangement with TPM3 generates the TRK transcript by fusing TPM3 to the 3'-end of NTRK1 (PubMed:2869410). An intrachromosomal rearrangement that links the protein kinase domain of NTRK1 to the 5'-end of the TPR gene forms the fusion protein TRK-T1. TRK-T1 is a 55 kDa protein reacting with antibodies against the C-terminus of the NTRK1 protein (PubMed:1532241). {ECO:0000269|PubMed:1532241, ECO:0000269|PubMed:2869410, ECO:0000269|PubMed:7565764}.;
