Q-omics provides the consensus-scored IGKV2D-30 profile across patient tissues and cancer cell-line models. IGKV2D-30 expression is associated with patient survival in 23 of 34 cancer types, with the highest sampling consensus in HNSC. Among the 18 cancer types available for tumor–normal comparison, IGKV2D-30 is differentially expressed in 8, with the highest sampling consensus in COAD. Additionally, IGKV2D-30 RNA expression shows 8,769 significant protein co-abundance associations, with the highest sampling consensus in LSCC. Together, these results highlight HNSC, COAD, and LSCC as cancer lineages where IGKV2D-30 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 summarizes IGKV2D-30 survival associations across molecular data types. IGKV2D-30 RNA expression shows survival associations in the most cancer types (23), followed by mutation status (1) and mass-spec protein abundance (2). The rightmost column indicates the cancer type with the highest sampling consensus for each molecular layer.
This table ranks reproducible IGKV2D-30 RNA expression–survival associations across cancer types. High IGKV2D-30 expression shows unfavorable associations in ACC and UVM, but favorable associations in HNSC, BRCA, SKCM and CESC. 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 IGKV2D-30 RNA expression.
This table summarizes IGKV2D-30 tumor–normal expression differences by data type. RNA shows broader differences across cancer types, with a lineage consensus of 8, while mass-spec protein shows differences in 2. The strongest signals are observed in COAD for RNA and LSCC for protein.
This table ranks reproducible tumor–normal expression differences for IGKV2D-30. A negative fold-change indicates higher expression in normal tissue than in tumor tissue. IGKV2D-30 shows lower tumor expression in COAD, BRCA, READ and STAD and higher tumor expression in LUAD and KIRC. The COAD box plot shows higher IGKV2D-30 RNA expression in normal versus tumor tissue (log2 FC = −2.822, t-test p < 0.001).
This table shows molecular features associated with IGKV2D-30 in patient tissues and cancer cell lines. In patient samples, IGKV2D-30 shows the broadest associations at the RNA and protein expression levels, with LSCC recurring as the lineage with the largest associated feature set.
