Across TCGA pan-cancer cohorts, MSX1 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated MSX1 data layer compared with 25 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher MSX1 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated MSX1 expression acts as an unfavorable survival marker.
HNSC, SKCM, and PRAD are the cancer types where MSX1 Mutation most reproducibly stratifies survival.
