Managing the Genetics of Chondrodystrophy (CDDY)

Chondrodystrophy occurs in many breeds, changing the character of all of the intervertebral discs at a young age and causing degenerative processes that predispose the discs to herniate. Unlike other disease-causing mutations found in dogs, the mutation that causes chondrodystrophy is not a change within a gene but is instead the insertion of an extra copy of a gene to a new location on a different chromosome.
