Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PP2PP3BS2
The NM_006206.6(PDGFRA):c.1790G>A(p.Arg597Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000219 in 1,460,536 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R597W) has been classified as Uncertain significance.

Gastrointestinal stromal tumor Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 23, 2023 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 597 of the PDGFRA protein (p.Arg597Gln). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with PDGFRA-related conditions. ClinVar contains an entry for this variant (Variation ID: 577328). 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 PDGFRA 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. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 03, 2023 | The p.R597Q variant (also known as c.1790G>A), located in coding exon 12 of the PDGFRA gene, results from a G to A substitution at nucleotide position 1790. The arginine at codon 597 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
