Ambry Genetics

Feb 06, 2023

The c.118G>T (p.A40S) alteration is located in exon 2 (coding exon 1) of the PARPBP gene. This alteration results from a G to T substitution at nucleotide position 118, causing the alanine (A) at amino acid position 40 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
