Genes affected

PDGFC (HGNC:8801): (platelet derived growth factor C) The protein encoded by this gene is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a core motif of eight cysteines. This gene product appears to form only homodimers. It differs from the platelet-derived growth factor alpha and beta polypeptides in having an unusual N-terminal domain, the CUB domain. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2010]

Ambry Genetics

Dec 21, 2023

The c.59C>T (p.T20I) alteration is located in exon 1 (coding exon 1) of the PDGFC gene. This alteration results from a C to T substitution at nucleotide position 59, causing the threonine (T) at amino acid position 20 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
