Across TCGA pan-cancer cohorts, MT-CYB RNA is linked to patient survival in 24 of 34 cancer types, making it the most broadly survival-associated MT-CYB data layer.
The strongest signal is observed in adrenocortical carcinoma (ACC), where higher MT-CYB RNA is associated with better disease-free survival. In most high-consensus cancer types, elevated MT-CYB expression acts as an unfavorable survival marker, although some lineages such as ACC and KIRP show a favorable association.
ACC, KIRP, and PAAD are the cancer types where MT-CYB RNA most reproducibly stratifies survival.
RNA survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
