The c.869C>T (p.P290L) alteration is located in exon 3 (coding exon 1) of the MAGEC2 gene. This alteration results from a C to T substitution at nucleotide position 869, causing the proline (P) at amino acid position 290 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
