To me, trisomy sounds like that the body is struggling with cell division (trying binary fision but without circular DNA), due to insufficient centrioles, so we prosper centrioles and use the compound from the Elysia chlorotica to draw them in, while hoping that the cells restore overtime, which unfortunately isn’t guaranteed.

Miscarriages could maybe be complicated, but the same procedure might help, while perhaps using multiple weake doses. I don’t have that much insight about that though. Trying to heal the fetus could be a risk.
Werner syndrome could maybe be a side effect, in case the cells divide more rapidly.
