The c.278A>G (p.Q93R) 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 278, causing the glutamine (Q) at amino acid position 93 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
