If you read the whole article this is what it states about CRD2, there may be similar diseases but it is not the same as CRD2.
What breeds of dog carry crd2? To date, the mutation causing crd2 has only been observed in one breed of dog, the APBT
. Researchers were somewhat surprised to learn that this mutation was not the cause of a very similar disease that occurs in a closely related breed, the American Staffordshire Terrier (Am.Staff.). The Am.Staff.’s disease has been termed Cone Rod Dystrophy 1 (crd1) and is currently being molecularly characterized. Because Pit Bulls and Am. Staffs share many common ancestors and interbreeding among these and other bull-type dogs is quite common, OptiGen will accept samples from any of the “bull” breeds for crd2 testing. It should be emphasized, however, that there is currently no evidence to suggest that crd2 is present in any breed besides the APBT
. Owners of pedigreed dogs that have been diagnosed by a veterinary ophthalmologist as having retinal degenerations (e.g. PRA or CRD) are encouraged to contact OptiGen to inquire about our Free DNA testing/Research program (OptiGen - Research
