I no longer have experience severe pain and stop my life just to be in the hospital for long periods of time.

My children no longer have a fear of losing their mom's. for long

and heard just how life-changing this treatment can be.

I'm able to work a full-time job and at one point in my life I stopped planning for the future because I felt

I didn't have one.

Now I can dream again without limitations.

It's now only a matter of time before gene editing moves from clinical trials to hospital

But there are still huge questions about access, price and the ethics of this cutting-edge therapy.

The Chinese scientist who sparked international controversy when he claimed he'd created the

world's first gene-edited babies has been jailed for three years.

So today we're asking how will gene editing change medicine and will everyone reap the rewards? From the Guardian, I mean sample and this is Science Weekly.

Hannah Devlin, you're a guardian science correspondent and you've been covering the

recent third international summit on genome editing. For people who know nothing

about gene editing what is it?

So gene editing is altering a person or an animal or plant's DNA and you can pretty much

think of it as editing a word document but in this case the

letters being changed are the letters in new genetic code so it could be adding in some
