The c.1915G>A (p.G639R) alteration is located in exon 14 (coding exon 13) of the VWA7 gene. This alteration results from a G to A substitution at nucleotide position 1915, causing the glycine (G) at amino acid position 639 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
