The c.1426G>A (p.G476S) alteration is located in exon 9 (coding exon 8) of the SLC6A16 gene. This alteration results from a G to A substitution at nucleotide position 1426, causing the glycine (G) at amino acid position 476 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
