Across TCGA pan-cancer cohorts, IGHD2-15 RNA is linked to patient survival in 18 of 34 cancer types, making it the most broadly survival-associated IGHD2-15 data layer.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher IGHD2-15 RNA is associated with better disease-free survival. In most high-consensus cancer types, elevated IGHD2-15 expression acts as an unfavorable survival marker, although some lineages such as HNSC and LUAD show a favorable association.
HNSC, UVM, and LUAD are the cancer types where IGHD2-15 RNA most reproducibly stratifies survival.
RNA survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
