Collection Method: clinical testing

The c.4403G>A (p.C1468Y) alteration is located in exon 25 (coding exon 25) of the VWDE gene. This alteration results from a G to A substitution at nucleotide position 4403, causing the cysteine (C) at amino acid position 1468 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
