The c.1378G>A (p.A460T) alteration is located in exon 11 (coding exon 9) of the ADAD1 gene. This alteration results from a G to A substitution at nucleotide position 1378, causing the alanine (A) at amino acid position 460 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
