Both curators and managers can edit a gene's settings. Managers however, also have an overview of all genes added to the system, accessible via the Setup area. This overview shows general information on all genes, including the number of variants. Selecting one of the genes allows a manager to view all of this gene's information.
To edit a gene's settings, curators go through the configuration area using the "Edit gene database" link, managers can also go through the setup area, using the "Edit gene" link from the gene's detailed view.
The form itself is similar to the creating new genes form.
