Genes affected

PARP4 (HGNC:271): (poly(ADP-ribose) polymerase family member 4) This gene encodes poly(ADP-ribosyl)transferase-like 1 protein, which is capable of catalyzing a poly(ADP-ribosyl)ation reaction. This protein has a catalytic domain which is homologous to that of poly (ADP-ribosyl) transferase, but lacks an N-terminal DNA binding domain which activates the C-terminal catalytic domain of poly (ADP-ribosyl) transferase. Since this protein is not capable of binding DNA directly, its transferase activity may be activated by other factors such as protein-protein interaction mediated by the extensive carboxyl terminus.

Ambry Genetics

Oct 27, 2022

The c.5137T>C (p.S1713P) alteration is located in exon 34 (coding exon 33) of the PARP4 gene. This alteration results from a T to C substitution at nucleotide position 5137, causing the serine (S) at amino acid position 1713 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
