Across TCGA pan-cancer cohorts, SAMD8 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated SAMD8 data layer compared with 25 for mass-spec protein and 2 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher SAMD8 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated SAMD8 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
HNSC and UCEC are the cancer types where SAMD8 Mutation most reproducibly stratifies survival.
