The c.1774G>T (p.G592W) alteration is located in exon 12 (coding exon 11) of the VWA7 gene. This alteration results from a G to T substitution at nucleotide position 1774, causing the glycine (G) at amino acid position 592 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
