Ambry Genetics

Aug 16, 2021

The c.149A>G (p.D50G) alteration is located in exon 2 (coding exon 2) of the VTA1 gene. This alteration results from a A to G substitution at nucleotide position 149, causing the aspartic acid (D) at amino acid position 50 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
