Ambry Genetics

Nov 24, 2024

The c.1247G>T (p.R416I) alteration is located in exon 13 (coding exon 12) of the PARP8 gene. This alteration results from a G to T substitution at nucleotide position 1247, causing the arginine (R) at amino acid position 416 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
