Across TCGA pan-cancer cohorts, GCN1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated GCN1 data layer compared with 26 for mass-spec protein and 9 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher GCN1 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated GCN1 expression acts as an unfavorable survival marker, although some lineages such as LUAD and LSCC show a favorable association.
CCRCC, LUAD, and LSCC are the cancer types where GCN1 mass-spec protein most reproducibly stratifies survival.
