The c.80G>T (p.G27V) alteration is located in exon 1 (coding exon 1) of the MAGI3 gene. This alteration results from a G to T substitution at nucleotide position 80, causing the glycine (G) at amino acid position 27 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
