Across TCGA pan-cancer cohorts, TMEM38A mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated TMEM38A data layer compared with 20 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher TMEM38A mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated TMEM38A expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
HNSC and LSCC are the cancer types where TMEM38A mass-spec protein most reproducibly stratifies survival.
