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 asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 986 of the PDGFRA protein (p.Asn986Ser). This variant is present in population databases (rs372859148, 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: 407433). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -

The p.N986S variant (also known as c.2957A>G), located in coding exon 21 of the PDGFRA gene, results from an A to G substitution at nucleotide position 2957. The asparagine at codon 986 is replaced by serine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
