Across TCGA pan-cancer cohorts, MVB12A mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated MVB12A data layer compared with 21 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher MVB12A mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated MVB12A expression acts as an unfavorable survival marker.
LSCC, GBM, and PDAC are the cancer types where MVB12A mass-spec protein most reproducibly stratifies survival.
