Genes affected
NTRK1 (HGNC:8031): (neurotrophic receptor tyrosine kinase 1) 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]

Variant summary: NTRK1 c.2002G>T (p.Asp668Tyr) results in a non-conservative amino acid change located in the Protein kinase domain profile (IPR000719) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.1e-06 in 246690 control chromosomes. c.2002G>T has been reported in the literature in multiple compound heterozygous individuals affected with Hereditary insensitivity to pain with anhidrosis (Miura_2000, Mardy_2001, Seo_2020, Cho_2024). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in reduced transformation activity (66%) of the receptor protein compared to that of wild type protein in in vitro cultured cells (Miranda_2002). The following publications have been ascertained in the context of this evaluation (PMID: 38581121, 32807182, 11159935, 11719521, 10982191, 32901917). ClinVar contains an entry for this variant (Variation ID: 21307). Based on the evidence outlined above, the variant was classified as pathogenic. -

It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.0000041, PM2). The variant was observed in trans with a pathogenic variant (NM_002529.3:c.851-33T>A) as compound heterozygous (3billion dataset, PM3).In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.843, 3Cnet: 0.970, PP3). Patient's phenotype is considered compatible with Insensitivity to pain, congenital, with anhidrosis (3billion dataset, PP4).The variant has been reported as pathogenic/likely pathogenic without evidence for the classification (ClinVar ID:VCV000021307.2). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This missense change has been observed in individual(s) with NTRK1-related conditions (PMID: 10982191, 28177573, 32807182, 32901917). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs80356677, gnomAD 0.006%). This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 668 of the NTRK1 protein (p.Asp668Tyr). This variant is also known as p.Asp674Tyr. For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Experimental studies have shown that this missense change affects NTRK1 function (PMID: 11719521). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt NTRK1 protein function. ClinVar contains an entry for this variant (Variation ID: 21307). -
