Genes affected
PDGFRA (HGNC:8803): (platelet derived growth factor receptor alpha) This gene encodes a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. Studies suggest that this gene plays a role in organ development, wound healing, and tumor progression. Mutations in this gene have been associated with idiopathic hypereosinophilic syndrome, somatic and familial gastrointestinal stromal tumors, and a variety of other cancers.

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. -
