Check this out. This is KJ and he just
0:03
made history before his first birthday.
0:05
He's the first person ever to get his
0:07
genes custom edited. KJ was born with a
0:10
rare genetic disorder where he couldn't
0:11
process protein. This causes ammonia to
0:14
build up in the blood, which can be
0:15
toxic to the brain. In fact, half of
0:17
babies diagnosed with KJ's disease die
0:20
within their first week of life. When a
0:21
group of researchers heard about KJ's
0:23
case, they knew that they could help.
0:25
You see, KJ's disease is the result of a
0:27
broken gene. He inherited a mutation
0:29
from each parent, and there's no working
0:31
copy of this gene. Researchers knew that
0:33
fixing this one place on his DNA, among
0:35
the billions of letters that make up his
0:37
genetic code, could help KJ. So, here's
0:40
what they did. First, they created a
0:42
molecular GPS using a gene editing
0:44
technology called Crisper. See, KJ's
0:47
custom crisper treatment would locate
0:48
the exact gene that needed fixing. Then,
0:52
they coaxed KJ's cells to correct that
0:54
DNA to create a new enzyme that
0:56
functions like normal. and it worked.
0:59
Now, it's still too soon to know if KJ
1:00
is cured forever or if he'll need future
1:02
treatments, but for now, he's doing
1:04
great. Other people have previously been
1:06
treated with crisper therapies for
1:07
genetic conditions, but this is the
1:09
first one customdesigned for a single
1:11
patient. I'm not exaggerating when I say
1:13
KJ's treatment may change the future of
1:16
medicine and the lives of millions of
1:18
people who live with genetic disorders.
1:20
A few years ago, this would have sounded
1:22
like sci-fi. Today, it's just science.
1:25
Follow me for more amazing science
1:26
stories and the occasional adorable
1:28
baby.
