Genes affected

PARP14 (HGNC:29232): (poly(ADP-ribose) polymerase family member 14) This gene encodes a member of the poly(ADP-ribose) polymerase (PARP) protein family. The encoded anti-apoptotic protein may regulate aerobic glycolysis and promote survival of cancer cells. Increased expression of this gene has been reported in a variety of tumor types.

The c.764G>T (p.G255V) alteration is located in exon 5 (coding exon 5) of the PARP14 gene. This alteration results from a G to T substitution at nucleotide position 764, causing the glycine (G) at amino acid position 255 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
