Across TCGA pan-cancer cohorts, RAB8B Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated RAB8B data layer compared with 21 for mass-spec protein and 7 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher RAB8B Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated RAB8B expression acts as an unfavorable survival marker.
LIHC, STAD, and SARC are the cancer types where RAB8B Mutation most reproducibly stratifies survival.
Mutation 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.
