Searching for information of a mutation in gene EGFR via the simple gene search interface. The panel 1 on the upper left corner is the search interface of HDAM and result table. The panel 2 on the right in the middle of the figure illustrates the content of a mutation page. Panel 3 on the top right corner shows the protein domain containing mutation and the protein structure 3D graph labeled with mutation via Jmol. Panel 4 on the bottom right conner shows the preferred path in PPI network (a) and the preferred PPI network (b).
