(H) Upset diagram demonstrating intersections of driver genes across six pan-cancer subtypes. The top panel presents counts of driver genes shared by each intersection, while the left panel corresponds to the total number of driver genes in each pan-cancer. Gray dots denote the absence of a corresponding intersection, while colored dots show sets participating in the intersection. Yellow, green, red, and black dots represent driver genes shared by six, four, three, and fewer than three pan-cancers, respectively. (I-N) Association of SAE1 mRNA expression levels with mutations in the six significantly driver genes identified in H. Significant correlations between SAE1 expression levels and driver gene mutations are displayed.
