As an affected adult, are there ways to have children who are not affected?

...Are there any additional risks for an affected woman during pregnancy? Are there any precautions she should take if she becomes pregnant?

PGD and prenatal screening will be useful, if the couple accepts the ethical implications. Risks for the pregnant woman consist of polyhydramnios, placenta previa, miscarriage, preterm birth, stillbirth, and complications in labor and delivery including prolonged labor, anesthesia risks and postpartum hemorrhage. Psychological risks, especially after having a baby with the congenital form, should be considered.
