The c.1380C>G (p.I460M) alteration is located in exon 10 (coding exon 10) of the MAGI3 gene. This alteration results from a C to G substitution at nucleotide position 1380, causing the isoleucine (I) at amino acid position 460 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
