Across TCGA pan-cancer cohorts, IGKV1D-27 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated IGKV1D-27 data layer compared with 20 for mass-spec protein.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher IGKV1D-27 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated IGKV1D-27 expression acts as an unfavorable survival marker.
GBM, LUAD, and LUSC are the cancer types where IGKV1D-27 Mutation most reproducibly stratifies survival.
Mutation 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.
