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]

This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 488 of the NTRK1 protein (p.Pro488Thr). This variant is present in population databases (rs764737760, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with NTRK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 456610). 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. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The c.1462C>A (p.P488T) alteration is located in exon 11 (coding exon 11) of the NTRK1 gene. This alteration results from a C to A substitution at nucleotide position 1462, causing the proline (P) at amino acid position 488 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
