Across TCGA pan-cancer cohorts, VMA21 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated VMA21 data layer compared with 24 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher VMA21 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated VMA21 expression acts as an unfavorable survival marker, although some lineages such as HNSC and COAD show a favorable association.
HNSC, COAD, and LUAD are the cancer types where VMA21 mass-spec protein most reproducibly stratifies survival.
