Across TCGA pan-cancer cohorts, SYNPO2L mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated SYNPO2L data layer compared with 23 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher SYNPO2L mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated SYNPO2L expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
HNSC are the cancer types where SYNPO2L mass-spec protein most reproducibly stratifies survival.
