The c.715A>G (p.I239V) alteration is located in exon 3 (coding exon 1) of the MAGEC2 gene. This alteration results from a A to G substitution at nucleotide position 715, causing the isoleucine (I) at amino acid position 239 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
