Ambry Genetics

Nov 30, 2022

The c.2054C>T (p.A685V) alteration is located in exon 21 (coding exon 21) of the ACAP3 gene. This alteration results from a C to T substitution at nucleotide position 2054, causing the alanine (A) at amino acid position 685 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
