Across TCGA pan-cancer cohorts, RRAS Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated RRAS data layer compared with 27 for mass-spec protein and 5 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher RRAS Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated RRAS expression acts as an unfavorable survival marker.
HNSC and STAD are the cancer types where RRAS Mutation most reproducibly stratifies survival.
