Across TCGA pan-cancer cohorts, MRM3 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated MRM3 data layer compared with 24 for mass-spec protein and 7 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher MRM3 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated MRM3 expression acts as an unfavorable survival marker.
HNSC, CESC, and BLCA are the cancer types where MRM3 Mutation most reproducibly stratifies survival.
