Collection Method: clinical testing

The c.1216G>A (p.G406S) alteration is located in exon 9 (coding exon 9) of the MAGI3 gene. This alteration results from a G to A substitution at nucleotide position 1216, causing the glycine (G) at amino acid position 406 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
