Q-omics provides the consensus-scored LINC01991 profile across patient tissues and cancer cell-line models. LINC01991 expression is associated with patient survival in 19 of 34 cancer types, with the highest sampling consensus in MESO. Among the 18 cancer types available for tumor–normal comparison, LINC01991 is differentially expressed in 5, with the highest sampling consensus in KIRC. Additionally, LINC01991 RNA expression shows 7,033 significant gene co-expression associations, with the highest sampling consensus in THYM. Together, these results highlight MESO, KIRC, and THYM as cancer lineages where LINC01991 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 LINC01991 survival associations across molecular data types. LINC01991 RNA expression shows survival associations in the most cancer types (19). The rightmost column indicates the cancer type with the highest sampling consensus for each molecular layer.
This table ranks reproducible LINC01991 RNA expression–survival associations across cancer types. High LINC01991 expression shows unfavorable associations in MESO, KIRP and KIRC, but favorable associations in SKCM, BLCA and PAAD. The MESO Kaplan–Meier curve shows clear separation, with the high-expression group declining faster, consistent with the unfavorable association (log-rank p = .002). Together, the overview and detailed table identify MESO as the clearest survival context for LINC01991 RNA expression.
This table summarizes LINC01991 tumor–normal expression differences by data type. RNA shows broader differences across cancer types, with a lineage consensus of 5. The strongest signals are observed in KIRC for RNA.
This table ranks reproducible tumor–normal expression differences for LINC01991. A negative fold-change indicates higher expression in normal tissue than in tumor tissue. LINC01991 shows lower tumor expression in KIRC, COAD, KICH and THCA and higher tumor expression in LUAD. The KIRC box plot shows higher LINC01991 RNA expression in normal versus tumor tissue (log2 FC = −0.386, t-test p < 0.001).
This table shows molecular features associated with LINC01991 in patient tissues and cancer cell lines. In patient samples, LINC01991 shows the broadest associations at the RNA and protein expression levels, with THYM recurring as the lineage with the largest associated feature set.
