Is your feature request related to a problem? Please describe.
Add clinvar link in external resources list.

Also, should we duplicate the UCSC link too in external resources?

And @ifokkema Can we add an LOVD link? What is the best format. It is a link that we just click and open a new browser.

You mean not to the syntax checker, but to the LOVD databases? Do you want this to be a blind link (e.g., "search for variant in LOVD"), or would you be willing to first fire an API call to see if the variant exists in LOVD at all, and then provide a direct link?
