The c.3023A>G (p.Y1008C) alteration is located in exon 26 (coding exon 26) of the VWA8 gene. This alteration results from a A to G substitution at nucleotide position 3023, causing the tyrosine (Y) at amino acid position 1008 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
