<p>Dear lazyweb,</p>

<p>I wonder how data are stored behind the <strong>Exac</strong> server http://exac.broadinstitute.org/ :</p>

<ul>
	<li>SQL only ?</li>
	<li>SQL+tabix/VCF ?</li>
	<li>Gemini ?</li>
	<li>...</li>
</ul>

<p>Thanks.</p>

<p>The source code is here:</p>

<p>https://github.com/konradjk/exac_browser</p>

<p>It looks like a MongoDB database and Python Flask webserver. It also builds on xBrowse:</p>
