Genes affected

MAGEC1 (HGNC:6812): (MAGE family member C1) This gene is a member of the melanoma antigen gene (MAGE) family. The proteins of this family are tumor-specific antigens that can be recognized by autologous cytolytic T lymphocytes. This protein contains a large number of unique short repetitive sequences in front of the MAGE-homologous sequence, and therefore is about 800 aa longer than the other MAGE proteins.

The c.275C>A (p.T92N) alteration is located in exon 4 (coding exon 2) of the MAGEC1 gene. This alteration results from a C to A substitution at nucleotide position 275, causing the threonine (T) at amino acid position 92 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
