Ambry Genetics

Nov 18, 2022

The c.800A>T (p.E267V) alteration is located in exon 8 (coding exon 8) of the VTA1 gene. This alteration results from a A to T substitution at nucleotide position 800, causing the glutamic acid (E) at amino acid position 267 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
