Across TCGA pan-cancer cohorts, TTLL1 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated TTLL1 data layer compared with 21 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher TTLL1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated TTLL1 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC are the cancer types where TTLL1 mass-spec protein most reproducibly stratifies survival.
