Across TCGA pan-cancer cohorts, MMRN2 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated MMRN2 data layer compared with 25 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher MMRN2 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated MMRN2 expression acts as an unfavorable survival marker, although some lineages such as CCRCC show a favorable association.
CCRCC, LUAD, and UCEC are the cancer types where MMRN2 mass-spec protein most reproducibly stratifies survival.
