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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2022The c.4360T>A (p.Y1454N) alteration is located in exon 31 (coding exon 30) of the PARP4 gene. This alteration results from a T to A substitution at nucleotide position 4360, causing the tyrosine (Y) at amino acid position 1454 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
