Ambry Genetics

Feb 07, 2023

The c.472G>T (p.A158S) alteration is located in exon 4 (coding exon 4) of the NAV2 gene. This alteration results from a G to T substitution at nucleotide position 472, causing the alanine (A) at amino acid position 158 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
