Across TCGA pan-cancer cohorts, GPN3 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated GPN3 data layer compared with 24 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher GPN3 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated GPN3 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
CCRCC, UCEC, and PDAC are the cancer types where GPN3 mass-spec protein most reproducibly stratifies survival.
