immunoglobulin kappa variable 1-8Genealiases: []

Q-omics provides the consensus-scored IGKV1-8 profile across patient tissues and cancer cell-line models. IGKV1-8 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, IGKV1-8 is differentially expressed in 7, with the highest sampling consensus in COAD. Additionally, IGKV1-8 RNA expression shows 10,462 significant protein co-abundance associations, with the highest sampling consensus in LSCC. Together, these results highlight HNSC, COAD, and LSCC as cancer lineages where IGKV1-8 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 IGKV1-8 survival associations across molecular data types. IGKV1-8 RNA expression shows survival associations in the most cancer types (24), followed by mass-spec protein abundance (1). The rightmost column indicates the cancer type with the highest sampling consensus for each molecular layer.

This table ranks reproducible IGKV1-8 RNA expression–survival associations across cancer types. High IGKV1-8 expression shows unfavorable associations in UVM, but favorable associations in HNSC, SKCM, UCEC, LUAD and SARC. 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 IGKV1-8 RNA expression.

This table ranks reproducible tumor–normal expression differences for IGKV1-8. A negative fold-change indicates higher expression in normal tissue than in tumor tissue. IGKV1-8 shows lower tumor expression in COAD, BRCA, READ and LIHC and higher tumor expression in LUAD and KIRC. The COAD box plot shows higher IGKV1-8 RNA expression in normal versus tumor tissue (log2 FC = −3.986, t-test p < 0.001).
