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 20, 2017 | In summary, this is a novel in-frame duplication with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the duplicated amino acid is currently unknown. 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 inserts 3 nucleotides in exon 22 of the PDGFRA mRNA (c.3096_3098dupGGA). This leads to the insertion of 1 amino acid residue in the PDGFRA protein (p.Glu1032dup) but otherwise preserves the integrity of the reading frame. - |
