SEC61G and glioblastoma: SEC61G and MARCH9, both of which exhibited significant overexpression related to SVs (Fig. 1b), showed different patterns from those of TGFB2 and IL10. MARCH9 showed statistical significance in some tumor types; considering the mean value of the differences in each tumor type, selective copy number gain was detected in CNS-GBM and Bone-Leiomyo.
