Across TCGA pan-cancer cohorts, PRMT1 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated PRMT1 data layer compared with 28 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PRMT1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PRMT1 expression acts as an unfavorable survival marker, although some lineages such as LUAD and GBM show a favorable association.
HNSC, PDAC, and COAD are the cancer types where PRMT1 mass-spec protein most reproducibly stratifies survival.
