Ambry Genetics

Aug 17, 2022

The c.392C>T (p.A131V) alteration is located in exon 2 (coding exon 2) of the CACTIN gene. This alteration results from a C to T substitution at nucleotide position 392, causing the alanine (A) at amino acid position 131 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
