The c.796G>A (p.G266R) alteration is located in exon 5 (coding exon 4) of the VASH2 gene. This alteration results from a G to A substitution at nucleotide position 796, causing the glycine (G) at amino acid position 266 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
