FDA Approves First-Ever Gene Therapy for Treatment of Genetic Hearing Loss

Although this affects a small number of people / kids per year - this is a great development. There's a related article^ which had a very moving account from a mom whose son has received this treatment.

  "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

Coincidentally, I'm reading this at the doctor's office reception, waiting to check my (potentially genetic) hearing loss. Hope it's something simpler, but good to know there are advances in this area.

This is a very cool example of a targeted gene therapy for a very specific type of hearing loss. As the article says it only applies to a subtype of genetic hearing loss which makes up 2-8% of genetic cases, but it’s nice to see such niche therapies being developed and approved despite the smaller number of people who could benefit. It underwent an accelerated review through a new program met to fast track treatments for rare conditions like this which would normally be difficult to get approved due to the small scale.

Very positive news. I have something similar but in a much more difficult gene with different manifestation, but at least this gives me hope that something might come up in 1-2 decades.

That's great! Kennedy's team is changing the world and how we see treatments. No more lifetime suppression of symptoms, more cures!

This is good news, but I still have concerns.

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.
