Ambry Genetics

May 30, 2024

The c.65G>A (p.S22N) alteration is located in exon 1 (coding exon 1) of the FSCN3 gene. This alteration results from a G to A substitution at nucleotide position 65, causing the serine (S) at amino acid position 22 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
