The c.4037G>A (p.C1346Y) alteration is located in exon 21 (coding exon 21) of the VWDE gene. This alteration results from a G to A substitution at nucleotide position 4037, causing the cysteine (C) at amino acid position 1346 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
