Across TCGA pan-cancer cohorts, VPS33A mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated VPS33A data layer compared with 22 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher VPS33A mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated VPS33A expression acts as an unfavorable survival marker, although some lineages such as PDAC and GBM show a favorable association.
CCRCC, HNSC, and PDAC are the cancer types where VPS33A mass-spec protein most reproducibly stratifies survival.
