Across TCGA pan-cancer cohorts, CNNM2 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated CNNM2 data layer compared with 19 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher CNNM2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated CNNM2 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LSCC show a favorable association.
CCRCC, LSCC, and LUAD are the cancer types where CNNM2 mass-spec protein most reproducibly stratifies survival.
