Across TCGA pan-cancer cohorts, RAB4A Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated RAB4A data layer compared with 21 for mass-spec protein and 7 for mass-spec protein.
The strongest signal is observed in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), where higher RAB4A Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated RAB4A expression acts as an unfavorable survival marker.
CESC, PRAD, and UCEC are the cancer types where RAB4A Mutation most reproducibly stratifies survival.
