The c.922A>T (p.M308L) alteration is located in exon 5 (coding exon 5) of the MAGI3 gene. This alteration results from a A to T substitution at nucleotide position 922, causing the methionine (M) at amino acid position 308 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
