An Idaho Court has ruled that a couple cannot sue for wrongful birth. Idaho has a specific statute that does not allow for any claim "but for the act or omission of another, a person would not have been permitted to have been born alive but would have been aborted." In New Jersey, there have been at least two wrongful death cases that settled out of court.
A few years ago there was a high profile wrongful birth case in France. Obviously, this has implications, both on medical practices, and for diability rights. Wrongful birth suits have since been prohibited by French law.
