Instructions for this Form - GDC Eye Registry Application
For application to the GDC Open Registry, the owner will fill out this form and 
submit it to the GDC along with the original or a copy of the opthalmologist's 
evaluation (one side of the white CERF owner's form).
When completed mail to: Institute for Genetic Disease Control in Animals, PO Box 
222, Davis, CA, 95617. Phone & Fax (916) 756-6773
When appropriate, the GDC issues a Certificate of Unaffected (valid for 1year). 
Otherwise the affected diagnosis is registered and the check is returned to the 
owner with notice of registration. The Open Eye Registry will be maintained in a 
breed specific manner, depending on the diseases found in each breed and the 
requests of the sponsoring breed club. 
Fees GDC Certification
No charge for affected entries.
$10 (US) for first unaffected Certification (valid for 1 year only, since 
symptoms may occur at any time).
$5 (US) for later unaffected Certification
$20 (US) when 5 or more littermates or related dogs are submitted at thesame 
time (no refund for affected)
Fees CERF Evaluation
The GDC will register CERF evaluations that are accompanied by this Application 
Form and:
$10 (US) if this is first GDC entry for the dog
$5 (US) if dog is already registered with GDC

About the Open Registry of Heredity Eye Diseases
The GDC Open Registry of Heredity Eye Diseases is a new tool to use in the fight 
against inherited eye diseases in all pure-bred canines. The owners of pure-bred 
dogs may now choose to place the evaluation of their dogs eyes in an open 
registry where it will be linked to other members of the dog's family. This 
information will identify carriers of inherited eye defects among the unaffected 
animals. A single dog's evaluation determines only the status of that individual 
dog - its phenotype. The phenotypes of a group of related dogs determines that 
groups genotype. 
In response to a formal request from the Poodle Club of America and with the 
cooperation of several organizations, the GDC is registering evaluations for 
inherited eye diseases. Research Databases are established for breeds which have 
not yet proven inheritance.
The Canine Eye Registration Foundation (CERF) is not associated with GDC. It 
will continue to operate as a protected registry by releasing data on normal 
animals only. Ophthalmic disease data gathered during CERF exams is only 
released as pooled information and no diseased animal is ever identified. The 
pooled data provides information on the prevalence of ophthalmic diseases by 
breed, age, sex, etc.
The new GDC Open Registry will file data for owners who wish to openly share the 
phenotypic evaluations of their dog, regardless of the diagnosis. The data can 
be used as the tool to determine genotypic risk factors (including carrier 
status) of an individual animal by linking all relatives that are submitted to 
the GDC Open Registry.
Information on Every Dog is Important
When there is data on a sufficiently large size family of dogs, a breeder can 
evaluate the risk for genetic disease transmission of dogs in that family.
The evaluations of every single dog, whether pet or working dog, become an 
important data source to increase the accuracy of the predicted risk in a 
relative being considered for breeding.
Access to the Open Registry
In general, data in the GDC Open Registry is available (for a fee) to people who 
need support and information which will lead to a reduction of geneticdiseases 
in a kennel or the breed. All information must be used in accord withethical 
breeding standards. All requests for information will be maintained in the file.
Examples of GDC Registry Use
A person (owner of either a male or a female animal) may ask for the evaluations 
of a disease in the siblings and half-sibs of their dog and a particular dog to 
be considered as a mate. They may ask for the same records on any progeny 
produced by their dog.
A researcher might propose a formal study of the data on one of the diseases, 
the method of diagnosis, the mode of inheritance, etc., with the expectation of 
Verification of Accuracy
An owner may request the GDC records on their own dog(s) at any time inorder to 
verify the accuracy of that information.
What is An Open Disease Registry?
An open disease registry is a data bank of genetic history for any breed of dog. 
In an open registry like the one maintained by the GDC (Institute for Genetic 
Disease Control in Animals), owners (potential breeders), veterinarians and 
scientists can trace the genetic history of any particular dog.
In order to control the increasing presence of genetic diseases (such as those 
of the hip, elbow, shoulder, eye, skin, heart), we must know how prevalent such 
diseases are in the breed and in any particular dog's bloodlines.
The information about each dog automatically becomes linked in the open registry 
with relatives of that animal. An open registry delivers this information to 
breeders for the selection of mates whose bloodlines indicate are reduced risk 
of producing genetic disease.
The purpose of the open registry is to help breeders and owners reduce the 
presence of genetic diseases in their breeds. In order to be effective, the 
registry must record data on as large a group of animals as possible, especially 
the affected.
Each owner of a registrant in an open registry has agreed to the release of the 
data whether the evaluation of the animal is affected or not. Each dog 
registered in an open registry brings crucial information to help support the 
improvement of the entire breed.
