Researchers show gene variant causes Hajdu-Cheney syndrome, may illuminate bone loss more generally

Fragile bones are usually an old person's affliction, but sometimes children are born with them. Now, a team of researchers led by UConn professor Ernesto Canalis has shown in mice that a specific gene can cause the disease, called Hajdu-Cheney syndrome. Overabundant bone-absorbing cells may be causing the disorder's characteristic bone loss, and the researchers hope to find a potential treatment.
