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]

The c.821C>A (p.T274K) alteration is located in exon 6 (coding exon 5) of the PDGFRL gene. This alteration results from a C to A substitution at nucleotide position 821, causing the threonine (T) at amino acid position 274 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
