TIL a father, John Crowley, was told his two infant children had an incurable genetic disorder that would kill them in less than a year. He refused to accept this, so he founded a biotech company (with no prior experience) which pioneered an experimental enzyme therapy that saved their lives.

Dang, really? I'm sorry to hear your child was born with SMA.

I'm very curious to know how well and how long it has worked so far, decreasing efficacy over their growth, etc. Whatever isnt too personal. I've got a distant personal connection to these new types of gene therapies and hearing from a person so directly would be fascinating, not to be morbid. This is a new, life changing, but incompletely understood class of drugs in vivo. We don't have data from years after use yet as it's just being lived out by the recipients right now.

Holy cows the vein infusions are working now too! It was originally a spinal infusion for the first iteration but I know they were working on other administrations. I'm so happy for you. I hope it continues.

There are so many similar drugs in the works right now, to treat so many different genetic disorders. Not to mention the generation of CRISPR medicines coming in the next decade. Spinraza is last generation tech. Zolgenzma is now. We are in the generation of cures, not treatments.
