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.

Ambry Genetics

Dec 17, 2023

The c.170G>T (p.R57L) alteration is located in exon 4 (coding exon 2) of the MAGEC1 gene. This alteration results from a G to T substitution at nucleotide position 170, causing the arginine (R) at amino acid position 57 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
