Genes affected

PDGFRL (HGNC:8805): (platelet derived growth factor receptor like) This gene encodes a protein with significant sequence similarity to the ligand binding domain of platelet-derived growth factor receptor beta. Mutations in this gene, or deletion of a chromosomal segment containing this gene, are associated with sporadic hepatocellular carcinomas, colorectal cancers, and non-small cell lung cancers. This suggests this gene product may function as a tumor suppressor. [provided by RefSeq, Jul 2008]

Oct 22, 2021

The c.833C>T (p.A278V) alteration is located in exon 6 (coding exon 5) of the PDGFRL gene. This alteration results from a C to T substitution at nucleotide position 833, causing the alanine (A) at amino acid position 278 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
