Ambry Genetics

Apr 20, 2023

The c.824T>C (p.I275T) alteration is located in exon 7 (coding exon 6) of the PARPBP gene. This alteration results from a T to C substitution at nucleotide position 824, causing the isoleucine (I) at amino acid position 275 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
