If someone has biological traits that make them a risk to others, then it is a problem of risk management. After all, one’s freedom ends where it encroaches on the freedom of others.

Thus, if a biological trait makes it likely, to a significant degree of statistical significance, that they will physically harm others, then the person with the trait should be given a choice: (a) have the trait modified or mitigated through medicine (if possible), (b) be monitored, or (c) be banished, to live among other high risk people.

If the trait and behavior have only slight statistical correlation, then the above choice should only be brought to bear when the person begins to show behavior that harms or actually puts others at risk. After all, as others have pointed out here, genes do not fully determine our fate.
