The c.3469A>G (p.I1157V) alteration is located in exon 26 (coding exon 26) of the GLG1 gene. This alteration results from a A to G substitution at nucleotide position 3469, causing the isoleucine (I) at amino acid position 1157 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
