The c.1472A>G (p.N491S) alteration is located in exon 15 (coding exon 15) of the GADL1 gene. This alteration results from a A to G substitution at nucleotide position 1472, causing the asparagine (N) at amino acid position 491 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
