Across TCGA pan-cancer cohorts, PRMT1 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PRMT1 data layer compared with 28 for mass-spec protein and 6 for mass-spec protein.
The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where higher PRMT1 Mutation 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 STAD show a favorable association.
KIRP, CESC, and ESCA are the cancer types where PRMT1 Mutation most reproducibly stratifies survival.
