The c.355A>G (p.T119A) alteration is located in exon 4 (coding exon 2) of the ADAD1 gene. This alteration results from a A to G substitution at nucleotide position 355, causing the threonine (T) at amino acid position 119 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
