25 outliers (top5%) of the significant clusters in all the three ontologies. The three ontologies are Cellular Component, Molecular Function and Biological Process. Each gene is identified by Gene Bank ID. The outliers are sorted by the distance from all the significant clusters. The gene names of the top 8 outliers which are located on the first line of the figure (from the left to right) are listed as follows: Neuronatin transcript variant 1, Homo sapiens citrate synthase (CS), Transthyretin, ESTs of Bone marrow macrophage, Mus musculus secreted acidic cysteine rich glycoprotein (Sparc), Mus musculus transthyretin (Ttr), Homo sapiens (FLJ13180 fis), Mus musculus estrogen receptor 1 (Esr1).
