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]

Apr 15, 2024

The c.16C>T (p.L6F) 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 16, causing the leucine (L) at amino acid position 6 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
