The c.4164G>T (p.R1388S) alteration is located in exon 22 (coding exon 22) of the VWDE gene. This alteration results from a G to T substitution at nucleotide position 4164, causing the arginine (R) at amino acid position 1388 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
