chr1-156876103-G-C
Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_002529.4(NTRK1):c.1525G>C(p.Asp509His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000743 in 1,614,096 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. D509N) has been classified as Uncertain significance.

Hereditary insensitivity to pain with anhidrosis Uncertain:3
- -
This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 503 of the NTRK1 protein (p.Asp503His). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 584602). 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. -

Inborn genetic diseases Uncertain:1
The c.1507G>C (p.D503H) alteration is located in exon 12 (coding exon 12) of the NTRK1 gene. This alteration results from a G to C substitution at nucleotide position 1507, causing the aspartic acid (D) at amino acid position 503 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
