Q-omics provides the consensus-scored IGKV1-12 profile across patient tissues and cancer cell-line models. IGKV1-12 expression is associated with patient survival in 24 of 34 cancer types, with the highest sampling consensus in HNSC. Among the 18 cancer types available for tumor–normal comparison, IGKV1-12 is differentially expressed in 7, with the highest sampling consensus in COAD. Additionally, IGKV1-12 RNA expression shows 13,694 significant protein co-abundance associations, with the highest sampling consensus in LSCC. Together, these results highlight HNSC, COAD, and LSCC as cancer lineages where IGKV1-12 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.

Survival associations

This table summarizes IGKV1-12 survival associations across molecular data types. IGKV1-12 RNA expression shows survival associations in the most cancer types (24). The rightmost column indicates the cancer type with the highest sampling consensus for each molecular layer.

This table ranks reproducible IGKV1-12 RNA expression–survival associations across cancer types. High IGKV1-12 expression shows unfavorable associations in KIRC, but favorable associations in HNSC, SKCM, CESC, BRCA and LUAD. The HNSC Kaplan–Meier curve shows clear separation, with the low-expression group declining faster, consistent with the favorable association (log-rank p < 0.001). Together, the overview and detailed table identify HNSC as the clearest survival context for IGKV1-12 RNA expression.

This table ranks reproducible tumor–normal expression differences for IGKV1-12. A negative fold-change indicates higher expression in normal tissue than in tumor tissue. IGKV1-12 shows lower tumor expression in COAD, BRCA, KICH and READ and higher tumor expression in LUAD and KIRC. The COAD box plot shows higher IGKV1-12 RNA expression in normal versus tumor tissue (log2 FC = −4.406, t-test p < 0.001).
