Across TCGA pan-cancer cohorts, GRPEL1 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated GRPEL1 data layer compared with 24 for mass-spec protein and 6 for mass-spec protein.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where higher GRPEL1 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated GRPEL1 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
BLCA, LUAD, and UCEC are the cancer types where GRPEL1 Mutation most reproducibly stratifies survival.
