Across TCGA pan-cancer cohorts, CNNM3 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CNNM3 data layer compared with 23 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CNNM3 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CNNM3 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LSCC show a favorable association.
CCRCC, LSCC, and UCEC are the cancer types where CNNM3 mass-spec protein most reproducibly stratifies survival.
