The c.1425G>T (p.Q475H) alteration is located in exon 10 (coding exon 10) of the MAGI3 gene. This alteration results from a G to T substitution at nucleotide position 1425, causing the glutamine (Q) at amino acid position 475 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
