Genes affected

MAGEE2 (HGNC:24935): (MAGE family member E2) This gene encodes a member of the E subfamily of MAGE (melanoma antigen-encoding gene) gene family. The gene is intronless and the encoded protein has two of the MAGE domains which are characteristic of MAGE family proteins. [provided by RefSeq, Sep 2011]

Collection Method: clinical testing

The c.905G>A (p.G302D) alteration is located in exon 1 (coding exon 1) of the MAGEE2 gene. This alteration results from a G to A substitution at nucleotide position 905, causing the glycine (G) at amino acid position 302 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
