PIK3R1

Across TCGA patient cohorts, PIK3R1 mutation is significantly associated with the RNA expression of many other genes, with 4,071 significant associations in total. UCEC shows the largest number of these associations.

The most reproducible PIK3R1-associated genes across cancer lineages are SAMM50, LILRB4, and FCGR3A. Each is linked with PIK3R1 in more than 3 cancer types. Because this analysis shows association rather than direction, both PIK3R1-to-partner and partner-to-PIK3R1 results are reported.

Each partner links to its own Q-omics profile. The box plot shows the strongest example, SAMM50 grouped by PIK3R1-low versus PIK3R1-high in UCEC.

mutation associated genes by consensus

Ranked by combined sampling and lineage consensus. X-score (PIK3R1→partner) and Y-score (partner→PIK3R1) are standardized regression coefficients; both directions are reported because the association is undirected. p-values are from the association test.
