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]

The NTRK1 c.295G>A; p.Val99Met variant (rs201509045, ClinVar Variation ID: 456616) is reported in the literature in an individuals affected with prostate cancer, though no other evidence of causality was presented (Liang 2022). This variant is found in the East Asian population with an allele frequency of 0.16% (32/19,942 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.335). Due to limited information, the clinical significance of this variant is uncertain at this time.

The c.295G>A (p.V99M) alteration is located in exon 3 (coding exon 3) of the NTRK1 gene. This alteration results from a G to A substitution at nucleotide position 295, causing the valine (V) at amino acid position 99 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
