The c.199G>A (p.G67S) alteration is located in exon 2 (coding exon 2) of the VWA1 gene. This alteration results from a G to A substitution at nucleotide position 199, causing the glycine (G) at amino acid position 67 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
