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.1248T>G (p.D416E) alteration is located in exon 6 (coding exon 6) of the PARP14 gene. This alteration results from a T to G substitution at nucleotide position 1248, causing the aspartic acid (D) at amino acid position 416 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
