No. What? Are you insane? If you knew that a couple were going to have a baby with whatever problems, and you did not inform them of this because in your mind, their decision might then somehow upset some other group of people who are neither the mother, nor the father, nor even the close family, then I would find that morally unacceptable.
EDIT: Although I disagree with your choice of example, I would also like to say, that I do think that there ethics is important in any profession, including in scientific research and publication.
EDIT 2: I think your reasoning and people who think like you comes from this (very American notion) of thinking that being homosexual or being deaf or being mute somehow makes you part of a "community". And then from this comes this idea of oppression when the community is deprived of one of their new prospective members. I find this whole thinking absurd.
