Across TCGA pan-cancer cohorts, CLN8 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated CLN8 data layer compared with 23 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher CLN8 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated CLN8 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LUAD show a favorable association.
PDAC, LSCC, and CCRCC are the cancer types where CLN8 mass-spec protein most reproducibly stratifies survival.
