Across TCGA pan-cancer cohorts, INMT mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated INMT data layer compared with 22 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher INMT mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated INMT expression acts as an unfavorable survival marker, although some lineages such as CCRCC and PDAC show a favorable association.
GBM, CCRCC, and PDAC are the cancer types where INMT mass-spec protein most reproducibly stratifies survival.
