Any edit action (addition, deletion, or confirmation) that you carry out for a variant is reflected in the font color and the Comments column for the variant in the Mutation report. This action is also automatically added to the audit trail for the variant. To view the edit history for a variant, right-click the variant in the Alignment viewer or in the Mutation report, and on the context menu that opens, click View Edit History to open the Edit History dialog box. The lower half of the Edit History dialog box displays all the edit operations that have been carried for the selected variant. The date and time and the username for the user who carried out the edit is displayed for each edit. When you select an edit entry in the lower pane, a selected series of old and new values is displayed in the upper half of the dialog box. If the edit resulted in a change for a variant value, then the old and new values are highlighted in red.
