IGKV1-9

Across TCGA patient cohorts, IGKV1-9 RNA expression is significantly associated with the protein abundance of many other proteins, with 15,209 significant associations in total. LSCC shows the largest number of these associations.

The most reproducible IGKV1-9-associated proteins across cancer lineages are IL16, MZB1, and SEPTIN1. Each is linked with IGKV1-9 in more than 9 cancer types. Because this analysis shows association rather than direction, both IGKV1-9-to-partner and partner-to-IGKV1-9 results are reported.

Each partner links to its own Q-omics profile. The scatter plot shows the strongest example, IGKV1-9 versus IL16 in BRCA, with a Pearson correlation of 0.70.

RNA expression associated proteins by consensus

Ranked by combined sampling and lineage consensus. X-score (IGKV1-9→partner) and Y-score (partner→IGKV1-9) are standardized regression coefficients; both directions are reported because the association is undirected. p-values are from the association test.

Lineage	Partner protein	X-score	Y-score	p(X)	p(Y)	Sampling consensus	Lineage consensus
BRCA	IL16 →	+0.640	+2.990	<.001	<.001	3	10
OV	MZB1 →	+1.454	+3.205	<.001	<.001	3	10
BRCA	SEPTIN1 →	+0.884	+3.171	<.001	<.001	3	9
BRCA	ISG20 →	+0.703	+2.302	<.001	<.001	3	9
