The c.2902A>G (p.I968V) alteration is located in exon 21 (coding exon 21) of the GLG1 gene. This alteration results from a A to G substitution at nucleotide position 2902, causing the isoleucine (I) at amino acid position 968 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
