As the other commenter pointed out, there are a number of diseases that have been pinpointed down to single gene mutations. There's a list of monogenetic disorders on the genome.gov page [1]. If this needed to be regulated in the same way as abortion to appease some folks, fine. Legal only to apply if you have one of these listed mutations. Eugenics gets brought up a lot as a strawman (see comment a few above), but the scientific and ethical reality is there's a huge difference between treating someone with... (a) a defective huntingtin gene (b) a gene we believe to be associated with a disease (c) a gene we believe to be associated with a superior outcome (e.g. intelligence) Conflating the three to the preclusion of addressing (a) is ethically criminal.
