The c.806A>G (p.N269S) alteration is located in exon 9 (coding exon 7) of the GLT8D1 gene. This alteration results from a A to G substitution at nucleotide position 806, causing the asparagine (N) at amino acid position 269 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
