The discovery of mutations associated with genetic diseases seems to be continually increasing. Regarding diagnostic testing for genetic diseases, there is no oversight or standardization of techniques. Veterinarians are therefore recommended to use laboratories that utilize validated tests with methodologies that have undergone peer-reviewed publication. In addition to utilizing validated testing, it is important for equine veterinarians to be familiar with genetic diseases of the breeds that they work with commonly.
