We have 1 more carrier girl and 2 more unaffected girls to work with, and if we want boys later in life we will probably wait for Decibel Therapeutics / Regeneron to finish their GJB-2 gene therapy before we have that child. If there are constraints then we will have a cochlear implant or simply not implant that embryo.
It was obvious to us how it should play out. My wife and I have an obligation to maximize the cone of possibility for our children and a duty to equip them best to experience the world so that they can choose the path through it that they wish.
Just like I would not pierce the eardrums of my child after she is born, I shall not intentionally choose an embryo that carries a debilitating condition that I cannot remedy or mitigate if I can choose otherwise. I don’t think this is a dilemma in any way. There is an obvious choice for us. We will not deny her normative sense organs. My parents got me glasses and contact lenses. My life would have been much less vibrant if they had chosen to not provide me those prosthetics.
Some parents are not so fortunate as us to have this choice. I hope modern therapeutics will enable all children and adults to have the full range of sensors that most humans carry.
