Prior to version 1.3, an empty section (section with no data) was not presented in the view mode. As of 1.3, this standard does not apply to the Genotype information and the newly added Consent section.
For an empty Consent section, I believe, it is enough to display the warning message.
I would also modify the wording of the warning from "None granted." to "No consent granted.".
The size of the fonts in the Consent section title is not standard. It should either be the same size as other section titles, or same font size as of the text displayed within section.
