MAGEE1 and glioma: Further, to determine the effect of copy number variation (CNV) on T2Ms expression, we compared their expression in glioma patients based on CNV data and observed no difference in expression of MAGEH1 (Figure 3B) and MAGEE1 (Figure 3C) between tumors with diploid and shallow deletion status, and between diploid and copy number gain status for the respective genes.
