My wife and I carry mutations to the gene so we’ve done preimplantation genetic testing to select the embryos that haven’t been affected and our daughter can hear just fine! We have enough unaffected embryos that we can have another child but if we can have a third we’d probably want a boy[0] and both of our male embryos are coincidentally affected. If somehow we’ve managed to delay long enough for the corresponding Decibel TX AAV.103 gene therapy to come to market, then this will be an incredible triumph of modern science and technology over nature.
Here’s hoping!
If you’re curious about this process, I’ve written about it here: https://wiki.roshangeorge.dev/w/IVF
And here’s the treatment pipeline image I nicked off decibel TX’s website before they were acquired a year and a half ago https://wiki.roshangeorge.dev/w/File:Screenshot_Decibel_Tx_P...
I’m super thrilled everything has gone through so fast.
0: it would just be nice to have children of both genders; a weak preference - if I have 3 daughters I would be thrilled anyway
Unfortunately, I have seen treatments arrive for almost every type of deafness except the one affecting me. I contracted the mumps at a very young age, approximately 5 months old, and I now have nerve deafness in one ear making me completely deaf in that ear. The ear drum still operates, as I feel pain in that ear when around extremely loud noises. I absolutely do not want a cochlear implant, so it seems I may be stuck like this for the rest of my life. :-(
"These kind of genetic therapies seem to reinforce this idea of deafness being a problem in need of eradication, and that the only solution for disabled people to fully assimilate into society is through a medical intervention," says Jaipreet Virdi
This just seems so incredibly stupid to me.Often times these are rare disease, even though there are some like type 1 diabete, and so they have very little research on them but the gene responsible for the disease are known.

My short interpretation is that you basically inject a virus to mutate cells permanently and it regrows missing hair that takes sound waves and turns them into electrical impulses in the brain.
Absolutely amazing!
Thank you.
Does gene therapy treatment correct the issue just in the individual, or does it also correct the genes inherited by the individual's children?
Otoferlin [1] uses calcium as a cofactor. These mutations happen for a reason. The enzyme is not only located in the ear, but also in the brain and bone marrow [2].
Will there be repercussions if the virus leaves the local area when the therapy is injected?
These OTOF mutation have their highest expression in the Turkish population. Many people with other variations of this gene only experience deafness when they have a fever[3]. So in my opinion, I would like to see ten year outcomes before celebrating.
