MAGED2 and cancer: The CTAs of the Melanoma antigen (Mage) family identified in the human and mouse genomes belong to two classes, according to their expression patterns: Mage-a and Mage-b genes, which are expressed predominantly in spermatogenic and cancer cells; and the ubiquitously expressed Mage-d, Mage-e, Mage-h1, and Mage-l2 genes [20, 28, 29, 41–43].
