Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4_ModerateBS2
The NM_006206.6(PDGFRA):c.3040G>A(p.Ala1014Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000242 in 1,613,500 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A1014G) has been classified as Uncertain significance.

Polyps, multiple and recurrent inflammatory fibroid, gastrointestinal Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Baylor Genetics | Oct 19, 2023 | - - |
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Apr 05, 2023 | In silico analysis supports 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
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 18, 2024 | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1014 of the PDGFRA protein (p.Ala1014Thr). This variant is present in population databases (rs768291477, gnomAD 0.005%). 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: 459081). 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 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 Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 28, 2022 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
