Ambry Genetics

Oct 03, 2023

The c.2607G>T (p.M869I) alteration is located in exon 23 (coding exon 23) of the VWA8 gene. This alteration results from a G to T substitution at nucleotide position 2607, causing the methionine (M) at amino acid position 869 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
