Across TCGA pan-cancer cohorts, RABGGTB mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated RABGGTB data layer compared with 23 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher RABGGTB mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated RABGGTB expression acts as an unfavorable survival marker, although some lineages such as UCEC and LSCC show a favorable association.
UCEC, CCRCC, and LUAD are the cancer types where RABGGTB mass-spec protein most reproducibly stratifies survival.
