Genes affected

PARP1 (HGNC:270): (poly(ADP-ribose) polymerase 1) This gene encodes a chromatin-associated enzyme, poly(ADP-ribosyl)transferase, which modifies various nuclear proteins by poly(ADP-ribosyl)ation. The modification is dependent on DNA and is involved in the regulation of various important cellular processes such as differentiation, proliferation, and tumor transformation and also in the regulation of the molecular events involved in the recovery of cell from DNA damage. In addition, this enzyme may be the site of mutation in Fanconi anemia, and may participate in the pathophysiology of type I diabetes. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 16, 2023

The c.2897G>A (p.G966D) alteration is located in exon 22 (coding exon 22) of the PARP1 gene. This alteration results from a G to A substitution at nucleotide position 2897, causing the glycine (G) at amino acid position 966 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
