Ambry Genetics

Dec 20, 2023

The c.281G>T (p.G94V) alteration is located in exon 3 (coding exon 1) of the MAGEC2 gene. This alteration results from a G to T substitution at nucleotide position 281, causing the glycine (G) at amino acid position 94 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
