PRA/PRCD TEST RESULTS
ALL OF OUR DOGS HAVE BEEN TESTED AND IN THE PROCESS OF BEING TESTED FOR PRA/PRCD. MORE RESULTS WILL BE POSTED SOON.
Here is some information to inform you about PRA/ PRCD
What does Normal/Clear (or
Homozygous Normal) mean? This means the dog
has no prcd-PRA gene, and therefore an extremely low risk of
developing prcd-PRA. This dog can be safely bred to any other dog, even a dog with
prcd-PRA,
and none of the puppies will be affected with prcd-PRA.
What does Carrier (or
Heterozygous) mean?
This means the dog
has only one prcd-PRA gene, and therefore an extremely low risk
of developing prcd-PRA. If bred, this dog would have a 50/50 chance of passing its one
prcd-PRA gene to its offspring. But remember, its other gene is normal, not
prcd-PRA, so
it also has a 50/50 chance of passing its normal gene to its offspring.
Since a puppy would need two prcd-PRA genes, one from each parent, in order to
develop prcd-PRA, this Carrier dog could be safely bred to a
Normal/Clear dog and none
of the puppies would develop prcd-PRA. Some of them might be
Normal/Clear (statistically, 50%) and some
of them might be Carriers (statistically, 50%), but none of them will be
affected with prcd-PRA. If this Carrier dog is bred to another
Carrier dog, however, there is a possibility
of producing prcd-PRA Affected puppies (statistically, 25%), but there is also the same possibility of
producing Normal/Clear puppies (again, statistically 25%). Some breeders might take this chance because
there aren't very many Normal/Clear dogs to breed to right now. But if they can
develop more of them by breeding two Carriers together, eventually we will have a
lot more Normal/Clear dogs. If your breeder has bred two Carriers together,
ask their reasons for doing so, and if you are satisfied with their answer, then
you may wish to consider having your puppy Optigen tested.
So what about Affected (or
Homozygous Mutant)?
This means the dog has two
prcd-PRA genes, and a very high chance of
developing prcd-PRA sometime during its lifetime. Currently that is estimated
to be anywhere from 3 to 13 years of age (or unknown actually). There are
a few Eskies out there who are 8-10 years old, Optigen tested as Affected, and still not showing any
symptoms of prcd-PRA. The good news about the Optigen test is that an
Affected dog can be safely bred to a Normal/Clear dog and no Affected puppies will be produced,
only Carriers. Which means, those puppies won't get prcd-PRA.
Breeding an Affected dog to a Carrier, however, is not recommended because it
would give the puppies a 50% chance of being prcd-PRA Affected themselves, and no chance
of being Normal/Clear.
All of our adults have been tested for PRA/PRCD.

PLL
Primary Lens Luxation according to OFA (Orthapedic Foundation for Animals ) a dog that is a carrier has a very low percentage 5-10% of developing primary lens luxation. Either the normal/clear copy or the mutated copy of the gene can be transmitted to its offspring. This means you can breed a carrier to a clear dog but can never breed an affected/high risk dog.
