Across TCGA pan-cancer cohorts, CHRDL1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CHRDL1 data layer compared with 21 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher CHRDL1 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CHRDL1 expression acts as an unfavorable survival marker, although some lineages such as HNSC and LSCC show a favorable association.
HNSC, PDAC, and LUAD are the cancer types where CHRDL1 mass-spec protein most reproducibly stratifies survival.
