Clear By Parentage Policy

What does “clear by parentage” mean?

OFA records results of approximately 120 DNA tests, all of which are currently “direct mutation” tests, meaning that the test results are 100 percent accurate and not subject to interpretation. For direct mutation tests, OFA will clear by parentage for one generation.

That means that if both parents have been DNA tested clear for a disease, OFA will declare offspring clear by virtue of the fact that the parents tested clear. However, there are a few requirements to clear by parentage.

1.) As mentioned, both sire and dam must have tested clear, and those test results must be on record with OFA.

2.) The sire, dam and the offspring to be cleared must all have been DNA identity profiled, and DNA profiles must be on record at OFA.

Once those requirements are met, the owner of the offspring to be cleared will fill out the application for DNA Based Genetic Disease (available on the OFA website), writing “clear by parentage” in the blank line at the top of the form, and submit the form with the $15 OFA processing fee. That’s it—your dog is now cleared by parentage for that disease.

The resulting certification will have a suffix of CBP, indicating that the dog itself was not tested and that the clearance is based on the sire and dam’s test results. OFA will only clear by parentage for one generation, due to the possibility of new mutations or as yet undiscovered gene mutations.

Bear in mind that DNA-based screening is an evolving science, and OFA policy is subject to change as technology and science advance.
