Protein-Protein interactions derived from one 'phenocluster' and genes lacking phenotype data. The figure shows an example for interactions between proteins from genes in a 'phenocluster'. Depicted is a network with many genes from the same 'phenocluster' (blue nodes with Entrez Gene IDs) for which associated proteins are connected, while the genes of all proteins that are responsible for these connections are not in our initial set of genes due to lack of substantial phenotype data (red nodes).
