Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2
The NM_006206.6(PDGFRA):c.1567T>A(p.Ser523Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000186 in 1,613,116 control chromosomes in the GnomAD database, with no homozygous occurrence. 13/22 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. S523Y) has been classified as Uncertain significance.

Submissions by phenotype
Polyps, multiple and recurrent inflammatory fibroid, gastrointestinal Uncertain:1
- -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Gastrointestinal stromal tumor Uncertain:1
This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 523 of the PDGFRA protein (p.Ser523Thr). This variant is present in population databases (rs147733970, gnomAD 0.01%). 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: 459010). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt PDGFRA protein function with a negative predictive value of 80%. 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
The p.S523T variant (also known as c.1567T>A), located in coding exon 10 of the PDGFRA gene, results from a T to A substitution at nucleotide position 1567. The serine at codon 523 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
