Ambry Genetics

Jun 16, 2022

The c.502G>A (p.V168I) alteration is located in exon 4 (coding exon 4) of the MXRA7 gene. This alteration results from a G to A substitution at nucleotide position 502, causing the valine (V) at amino acid position 168 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
