Ambry Genetics

Jul 06, 2021

The c.2044G>C (p.E682Q) alteration is located in exon 12 (coding exon 12) of the MAGI3 gene. This alteration results from a G to C substitution at nucleotide position 2044, causing the glutamic acid (E) at amino acid position 682 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
