You are lucky to know ahead of time about your respective mutations. We didn’t (no family history and both asymptomatic carriers) and my son was born bilateral profoundly deaf (connexin 26). We have chosen the path of cochlear implant (which is an amazing technology). We are both looking forward to seeing advancements in therapies for GJB2 mutations sparing many parents (and children) what we have been through. However, corrective therapy for GJB2 might require much earlier discovery of the issue and earlier administration I believe, as usually those variants affect actual physical growth of hair cells in the cochlea.
