Across TCGA pan-cancer cohorts, FAM126A mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated FAM126A data layer compared with 25 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher FAM126A mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated FAM126A expression acts as an unfavorable survival marker.
UCEC, CCRCC, and LSCC are the cancer types where FAM126A mass-spec protein most reproducibly stratifies survival.
