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 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
This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 789 of the PDGFRA protein (p.Gly789Asp). This variant is present in population databases (rs555553917, gnomAD 0.006%). 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: 459056). 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.G789D variant (also known as c.2366G>A), located in coding exon 16 of the PDGFRA gene, results from a G to A substitution at nucleotide position 2366. The glycine at codon 789 is replaced by aspartic acid, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
