Across TCGA pan-cancer cohorts, HIGD2A mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated HIGD2A data layer compared with 24 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HIGD2A mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated HIGD2A expression acts as an unfavorable survival marker, although some lineages such as HNSC and COAD show a favorable association.
HNSC, COAD, and UCEC are the cancer types where HIGD2A mass-spec protein most reproducibly stratifies survival.
