Beijing (CNN)With his black, brown and white fur, Longlong looks like most beagles. But the puppy has been sick with a blood-clotting disorder since birth — exactly what scientists in China had wanted.
The pup was cloned from Apple, a different dog whose genome was edited to develop the disease atherosclerosis.
With that genetic information now coded in, the disease — a leading cause of stroke and heart sickness — was passed along to Longlong, who scientists will use to study the condition and its possible cures.
Longlong’s creator, Beijing-based biotech company Sinogene, said Longlong is the world’s first dog cloned from a gene-edited donor. With Longlong’s birth, the scientists claimed that China had matched South Korea as a leader in canine cloning technology.
