Across TCGA pan-cancer cohorts, KIF26B mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated KIF26B data layer compared with 23 for mass-spec protein and 14 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher KIF26B mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated KIF26B expression acts as an unfavorable survival marker, although some lineages such as UCEC and HNSC show a favorable association.
UCEC, HNSC, and CCRCC are the cancer types where KIF26B mass-spec protein most reproducibly stratifies survival.
