The c.908A>G (p.Y303C) alteration is located in exon 5 (coding exon 5) of the MAGI3 gene. This alteration results from a A to G substitution at nucleotide position 908, causing the tyrosine (Y) at amino acid position 303 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
