Ambry Genetics

Apr 27, 2024

The c.1478G>A (p.G493D) alteration is located in exon 10 (coding exon 10) of the MAGI3 gene. This alteration results from a G to A substitution at nucleotide position 1478, causing the glycine (G) at amino acid position 493 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
