There are genetic screens for a few congenital disorders. A friend’s daughter was genetically screened for galactosemia and by catching it they almost certainly helped her have a normal life.

But since Gattaca was released, we’ve just continued to learn that it’s likely impossible to predict the full capability of a person from only DNA. There are too many variables in how genes are expressed, and the social context in which each person finds themselves.

That said, the real story of Gattaca is unjustified discrimination, and there are already plenty of technologies for that. So in that sense I think you’re right that it’s already among us. Just as it was in 1997… Gattaca is a pretty transparent allegory.
