Across TCGA pan-cancer cohorts, APOBEC4 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated APOBEC4 data layer compared with 22 for mass-spec protein.
The strongest signal is observed in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), where higher APOBEC4 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated APOBEC4 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
CESC, LIHC, and UCEC are the cancer types where APOBEC4 Mutation most reproducibly stratifies survival.
