Collection Method: clinical testing

The c.4439A>T (p.Y1480F) alteration is located in exon 25 (coding exon 25) of the VWDE gene. This alteration results from a A to T substitution at nucleotide position 4439, causing the tyrosine (Y) at amino acid position 1480 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
