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.

Collection Method:clinical testing

The c.179C>T (p.P60L) alteration is located in exon 1 (coding exon 1) of the PARP14 gene. This alteration results from a C to T substitution at nucleotide position 179, causing the proline (P) at amino acid position 60 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
