Ambry Genetics

Sep 01, 2021

The c.497G>A (p.G166E) alteration is located in exon 4 (coding exon 4) of the NAV2 gene. This alteration results from a G to A substitution at nucleotide position 497, causing the glycine (G) at amino acid position 166 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
