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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.920G>A (p.S307N) alteration is located in exon 6 (coding exon 6) of the PARP16 gene. This alteration results from a G to A substitution at nucleotide position 920, causing the serine (S) at amino acid position 307 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
