A hopeful thread! Some of my favs:
HIV treatment is better by leaps and bounds, and now 2x year injections can prevent people from contracting it! www.npr.org/sections/goa...

The first child treated with a new gene therapy designed to safely reach deep into the brain died just days after dosing

If tied to treatment, this would be the 5th death linked to gene therapy in the past year. Since 2019, there have been at least 13

Child dies after receiving new experimental gene therapy
The first child to receive a new experimental gene therapy for a rare neurological disorder died a few days after dosing, the company sponsoring the trial said.

Wild to see a thread about me. I think the broader topic (as Jason points out) is what does the future of preventive medicines look like for at risk gene carriers? I also hope this gives people some hope to those dealing with devastating and (previously) unactionable inherited genetic diseases.

A 🧵: Last week, I wrote about Jeff Vierstra, who carries the gene for a devastating, rare form of ALS. The disease killed his mom and all three of her siblings, along with relatives dating back to the 1800s.

Then, in 2020, two of his sisters began showing symptoms.
Did a drug prevent this man’s ALS?
Jeff Vierstra was likely doomed by his DNA. A radical experiment gave him a chance to rewrite his fate — before ALS symptoms ever began.

Trump proposes to rescind AIDS funds. Congress rejects the proposal. So Trump and his henchman Russ Vought just refuse to spend the money and try to hide that decision from Congress and the public. www.nytimes.com/2025/08/21/h...

It was also a bold first experiment of an approach that may one day be applied to thousands of other people living with what can feel like ticking time bombs wired into their DNA: Genes for Huntington's disease, familial forms of Alzheimer's and ALS, Prion disease, among others

But the results were "abnormal." Given his gene, the doctor feared he was seeing early, silent signs of ALS. He wanted to put Jeff on the drug, despite the serious risks it might entail. The drug, largely untested, could do significant damage.

It was an effort to save Jeff's life and prevent ALS

Then, in 2020, two of his sisters began showing symptoms. Thanks to a chance-meeting, they were each given early access to an experimental drug designed to suppress the toxic gene.

Jeff then got his own nerve-function test. The results worried his neurologist. He didn't have ALS — not yet at least

In an event celebrating the 35th anniversary of the passage of the Americans with Disabilities Act, HHS Secretary Kennedy spent 8ish minutes talking about how his family started the Special Olympics, his disabled aunt Rosemary, and democracy. He then posed for a picture.

He did not mention the ADA.
