Genes affected

MAGEC3 (HGNC:23798): (MAGE family member C3) This gene is a member of the MAGEC gene family. The members of this family are not expressed in normal tissues, except for testis, and are expressed in tumors of various histological types. The MAGEC genes are clustered on chromosome Xq26-q27. Two transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.656C>T (p.T219M) alteration is located in exon 4 (coding exon 4) of the MAGEC3 gene. This alteration results from a C to T substitution at nucleotide position 656, causing the threonine (T) at amino acid position 219 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
