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.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 24, 2017 | The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in PDGFRA cause disease. Therefore, this variant has been classified as a Variant of Uncertain Significance. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a PDGFRA-related disease. This sequence change deletes 1 nucleotide from exon 22 of the PDGFRA mRNA (c.2893delA), causing a frameshift at codon 965. This creates a premature translational stop signal (p.Ile965Phefs*6) and is expected to result in an absent or disrupted protein product. - |
