Genes affected

PARP16 (HGNC:26040): (poly(ADP-ribose) polymerase family member 16) Enables kinase binding activity; pentosyltransferase activity; and protein serine/threonine kinase activator activity. Involved in several processes, including IRE1-mediated unfolded protein response; positive regulation of protein serine/threonine kinase activity; and protein ADP-ribosylation. Located in endoplasmic reticulum tubular network and nuclear envelope. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.716G>A (p.R239Q) alteration is located in exon 5 (coding exon 5) of the PARP16 gene. This alteration results from a G to A substitution at nucleotide position 716, causing the arginine (R) at amino acid position 239 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
