Genes affected

PDGFD (HGNC:30620): (platelet derived growth factor D) 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, seven of which are found in this factor. This gene product only forms homodimers and, therefore, does not dimerize with the other three family members. It differs from alpha and beta members of this family in having an unusual N-terminal domain, the CUB domain. Two splice variants have been identified for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 17, 2021

The c.770A>G (p.K257R) alteration is located in exon 5 (coding exon 5) of the PDGFD gene. This alteration results from a A to G substitution at nucleotide position 770, causing the lysine (K) at amino acid position 257 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
