From: Gene signature-based mapping of immunological systems and diseases
Similarity matrix of immune disease gene signatures. One hundred fifty-five Immune disease gene signatures were paired against each other. Similarity was calculated by Fisher’s exact test of overlapping genes for each pair. Gene signatures from the same disease category were positioned together. Color represents the –log (P value of Fisher’s exact test), with red color indicating high similarity, and blue color indicating less/no similarity. Black boxes group the gene signatures that represent the same disease category
