Nov 27, 2023

The c.625A>G (p.I209V) alteration is located in exon 7 (coding exon 5) of the ADAD1 gene. This alteration results from a A to G substitution at nucleotide position 625, causing the isoleucine (I) at amino acid position 209 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
