<i>Also, I don&#x27;t think 23&amp;Me&#x27;s test results have enough medical value to be used for evaluating health risks.</i><p>For some things they do, like they test for mutations related to Alzheimer&#x27;s that can drastically alter risk, ranging from &quot;you&#x27;re probably never going to get it&quot; to &quot;you&#x27;re probably going to get it, and there&#x27;s a good chance it&#x27;ll be much earlier than you would have imagined&quot;.<p>But their marketing material was vastly overstating the value of their results, which is near 0 for most diseases. And it was misleading people into thinking it was more comprehensive than it really was (like, it&#x27;s not a full genome, and it doesn&#x27;t include every SNP that we know matters like most BRCA mutations).
