Ambry Genetics

Dec 22, 2023

The c.668A>G (p.N223S) alteration is located in exon 4 (coding exon 3) of the ADNP2 gene. This alteration results from a A to G substitution at nucleotide position 668, causing the asparagine (N) at amino acid position 223 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
