Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_002529.4(NTRK1):c.356G>A(p.Arg119His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000428 in 1,613,122 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R119C) has been classified as Uncertain significance.

Hereditary insensitivity to pain with anhidrosis Uncertain:3

This sequence change replaces arginine with histidine at codon 119 of the NTRK1 protein (p.Arg119His). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs778566154, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with NTRK1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -

Inborn genetic diseases Uncertain:1
The p.R119H variant (also known as c.356G>A), located in coding exon 3 of the NTRK1 gene, results from a G to A substitution at nucleotide position 356. The arginine at codon 119 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
