0:00Check this out. This is KJ and he just

0:03made history before his first birthday.

0:05He's the first person ever to get his

0:07genes custom edited. KJ was born with a

0:10rare genetic disorder where he couldn't

0:11process protein. This causes ammonia to

0:14build up in the blood, which can be

0:15toxic to the brain. In fact, half of

0:17babies diagnosed with KJ's disease die

0:20within their first week of life. When a

0:21group of researchers heard about KJ's

0:23case, they knew that they could help.

0:25You see, KJ's disease is the result of a

0:27broken gene. He inherited a mutation

0:29from each parent, and there's no working

0:31copy of this gene. Researchers knew that

0:33fixing this one place on his DNA, among

0:35the billions of letters that make up his

0:37genetic code, could help KJ. So, here's

0:40what they did. First, they created a

0:42molecular GPS using a gene editing

0:44technology called Crisper. See, KJ's

0:47custom crisper treatment would locate

0:48the exact gene that needed fixing. Then,

0:52they coaxed KJ's cells to correct that

0:54DNA to create a new enzyme that

0:56functions like normal. and it worked.

0:59Now, it's still too soon to know if KJ

1:00is cured forever or if he'll need future

1:02treatments, but for now, he's doing

1:04great. Other people have previously been

1:06treated with crisper therapies for

1:07genetic conditions, but this is the

1:09first one customdesigned for a single

1:11patient. I'm not exaggerating when I say

1:13KJ's treatment may change the future of

1:16medicine and the lives of millions of

1:18people who live with genetic disorders.

1:20A few years ago, this would have sounded

1:22like sci-fi. Today, it's just science.

1:25Follow me for more amazing science

1:26stories and the occasional adorable

1:28baby.
