Thoughts on Gene therapy

They say that Gene therapy could be the possible cure for pku.  It sounds like amazing idea. There are alot of risks. To the pku community minus all the sciencetist. Regular individuals like you and me. Don't know a whole lot about it. Alot of questions I wonder about is... What are the risks? They say it's a one time fix... But is that really the case? How would it work? Could your body reject over time? Is it even safe to get pregnant after taking it? So many unanswered questions. Makes me worried to even be willing to try it. But in cases like these with very little info to go off. You gotta keep your mind wide open. I really hope they find a cure some day. ❤️
