Q-omics provides the consensus-scored IGKV3-31 profile across patient tissues and cancer cell-line models. IGKV3-31 expression is associated with patient survival in 11 of 34 cancer types, with the highest sampling consensus in ESCA. Among the 18 cancer types available for tumor–normal comparison, IGKV3-31 is differentially expressed in 1, with the highest sampling consensus in BRCA. Additionally, IGKV3-31 RNA expression shows 6,203 significant pathway-activity associations, with the highest sampling consensus in STAD. Together, these results highlight ESCA, BRCA, and STAD as cancer lineages where IGKV3-31 shows reproducible signals across survival, tumor–normal expression, and patient cross-omics analyses.

Every result is evaluated using two consensus scores. Sampling consensus measures how consistently a finding is reproduced within a cancer lineage across different conditions. Lineage consensus measures how broadly the result is shared across cancer types, distinguishing pan-cancer signals from lineage-specific patterns.

This table ranks reproducible IGKV3-31 RNA expression–survival associations across cancer types. High IGKV3-31 expression shows unfavorable associations in ESCA, SKCM, LUSC, KIRC, STAD and COAD. The ESCA Kaplan–Meier curve shows clear separation, with the high-expression group declining faster, consistent with the unfavorable association (log-rank p = .008). Together, the overview and detailed table identify ESCA as the clearest survival context for IGKV3-31 RNA expression.
