IGKV1-8

Across TCGA patient cohorts, IGKV1-8 protein abundance is significantly associated with the RNA expression of many other genes, with 4,037 significant associations in total. LSCC shows the largest number of these associations.

The most reproducible IGKV1-8-associated genes across cancer lineages are IGHG4, IGKV1-17, and BABAM2. Each is linked with IGKV1-8 in more than 2 cancer types. Because this analysis shows association rather than direction, both IGKV1-8-to-partner and partner-to-IGKV1-8 results are reported.

Each partner links to its own Q-omics profile. The scatter plot shows the strongest example, IGKV1-8 versus IGHG4 in PDAC, with a Pearson correlation of 0.35.

protein abundance associated genes by consensus

Ranked by combined sampling and lineage consensus. X-score (IGKV1-8→partner) and Y-score (partner→IGKV1-8) are standardized regression coefficients; both directions are reported because the association is undirected. p-values are from the association test.
