Collection Method: clinical testing

The c.4684G>C (p.G1562R) alteration is located in exon 28 (coding exon 28) of the VWDE gene. This alteration results from a G to C substitution at nucleotide position 4684, causing the glycine (G) at amino acid position 1562 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
