&gt; In patients with schizophrenia, a variation in a single position in the DNA sequence marks too many synapses for removal and that pruning goes out of control. The result is an abnormal loss of gray matter.<p>I find this to be a terrifying thought. Just the idea that I have some code inside me that&#x27;s marking synapses for removal, and then they get removed. Those are my memories!<p>But I&#x27;m very excited about this. I&#x27;m not a geneticist by any means, but I hope the answer is as simple as replacing this gene with CRISPR.
