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.

Dec 27, 2023

The c.259G>A (p.V87I) alteration is located in exon 2 (coding exon 2) of the PARP14 gene. This alteration results from a G to A substitution at nucleotide position 259, causing the valine (V) at amino acid position 87 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
