Ambry Genetics

May 25, 2023

The c.218A>G (p.Q73R) alteration is located in exon 3 (coding exon 3) of the VTA1 gene. This alteration results from a A to G substitution at nucleotide position 218, causing the glutamine (Q) at amino acid position 73 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
