Ambry Genetics

Feb 14, 2023

The c.563C>T (p.A188V) alteration is located in exon 1 (coding exon 1) of the NACA2 gene. This alteration results from a C to T substitution at nucleotide position 563, causing the alanine (A) at amino acid position 188 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
