Across TCGA pan-cancer cohorts, KMO mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated KMO data layer compared with 26 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher KMO mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated KMO expression acts as an unfavorable survival marker.
CCRCC, LUAD, and GBM are the cancer types where KMO mass-spec protein most reproducibly stratifies survival.
