Across TCGA pan-cancer cohorts, PRMT9 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PRMT9 data layer compared with 24 for mass-spec protein and 3 for mass-spec protein.
The strongest signal is observed in kidney chromophobe (KICH), where higher PRMT9 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated PRMT9 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
KICH, ACC, and UCEC are the cancer types where PRMT9 Mutation most reproducibly stratifies survival.
