The c.3286C>G (p.R1096G) alteration is located in exon 1 (coding exon 1) of the IRS1 gene. This alteration results from a C to G substitution at nucleotide position 3286, causing the arginine (R) at amino acid position 1096 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
