The c.925A>G (p.R309G) alteration is located in exon 7 (coding exon 7) of the VSIG2 gene. This alteration results from a A to G substitution at nucleotide position 925, causing the arginine (R) at amino acid position 309 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
