It exists in fiction.
>Double-Y syndrome is a genetic mutation present in some males in the 22nd century. Specifically, it is a deformity of the X/Y chromosome pair, resulting in the YY pattern. This pattern gives the afflicted person (who, by definition, will always be male) a predisposition for antisocial behavior, specifically very brutal crimes, including rape and serial murder of women.
>Owing to their dangerous nature, double-Y syndrome convicts are typically detained in separate facilities from other convicted criminals. One such double-Y prison facility was the Fiorina 161 Class C Work Correctional Unit, which originally housed five thousand inmates, all double-Y syndrome sufferers.
