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 alteration is classified as 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. -

The PDGFRA c.1388C>G (p.Thr463Ser) missense change has a maximum subpopulation frequency of 0.068% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. To our knowledge, this variant has not been reported in individuals with PDGFRA-related conditions. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Significance: Uncertain significance
Review Status: no assertion criteria provided
Collection Method: clinical testing

The PDGFRA c.1388C>G variant is predicted to result in the amino acid substitution p.Thr463Ser. This variant was reported in an individual with sarcoma (Jouenne et al. 2017. PubMed ID: 28592523). This variant is reported in 0.069% of alleles in individuals of South Asian descent in gnomAD and has conflicting interpretations of pathogenicity in ClinVar ranging from likely benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/240305/). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
