Ambry Genetics

Dec 18, 2023

The c.128G>A (p.S43N) alteration is located in exon 1 (coding exon 1) of the NAV2 gene. This alteration results from a G to A substitution at nucleotide position 128, causing the serine (S) at amino acid position 43 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
