Across TCGA pan-cancer cohorts, CBX6 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CBX6 data layer compared with 23 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CBX6 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CBX6 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LUAD show a favorable association.
CCRCC, LUAD, and HNSC are the cancer types where CBX6 mass-spec protein most reproducibly stratifies survival.
