The c.765G>T (p.Q255H) alteration is located in exon 12 (coding exon 11) of the PARP8 gene. This alteration results from a G to T substitution at nucleotide position 765, causing the glutamine (Q) at amino acid position 255 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
