The c.586G>A (p.A196T) alteration is located in exon 3 (coding exon 1) of the MAGEC2 gene. This alteration results from a G to A substitution at nucleotide position 586, causing the alanine (A) at amino acid position 196 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
