Ambry Genetics

Aug 14, 2023

The c.137C>T (p.A46V) alteration is located in exon 2 (coding exon 1) of the PARPBP gene. This alteration results from a C to T substitution at nucleotide position 137, causing the alanine (A) at amino acid position 46 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
