Sep 01, 2021

The c.26A>G (p.Q9R) alteration is located in exon 3 (coding exon 1) of the ADAD1 gene. This alteration results from a A to G substitution at nucleotide position 26, causing the glutamine (Q) at amino acid position 9 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
