Aug 01, 2022

The c.83C>T (p.A28V) alteration is located in exon 3 (coding exon 1) of the MAGEA12 gene. This alteration results from a C to T substitution at nucleotide position 83, causing the alanine (A) at amino acid position 28 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
