This tool draws networks connecting genes that have been associated to different diseases. The user can select within three different disease gene lists using the radio button below. The resulting connection-graphs can be displayed at three level of complexity. Level 1 (connect): only direct interactions between disease genes are shown. Level 2 (Add bridge proteins) disease genes that connect via bridge proteins are also shown. Level 3 (all): all the interactions of the disease genes annotated in SIGNOR are shown.
