Genes affected

MAGED1 (HGNC:6813): (MAGE family member D1) This gene is a member of the melanoma antigen gene (MAGE) family. Most of the genes of this family encode tumor specific antigens that are not expressed in normal adult tissues except testis. Although the protein encoded by this gene shares strong homology with members of the MAGE family, it is expressed in almost all normal adult tissues. This gene has been demonstrated to be involved in the p75 neurotrophin receptor mediated programmed cell death pathway. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.190C>T (p.P64S) alteration is located in exon 3 (coding exon 2) of the MAGED1 gene. This alteration results from a C to T substitution at nucleotide position 190, causing the proline (P) at amino acid position 64 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
