New DNA Test for one form of PRA in Basenjis

[DebraDownSouth]

Since the test is only for one type, which is a start, if she is a carrier then you're still stuck with a lot of database analysis/info/word of mouth on any PRA in the sire's side. I know YOU know that, but anyone reading might think that just the PRA test available now means all clear. She could actually be a carrier for other types, as could clear dogs, etc.

Pat do you think the high numbers represent the breed or is it that those who have reasons to be concerned already are the first ones testing and hence the high numbers?

[tanza]

I think the high number does represent the breed. Could be that some if it is because people are/were concerned, but I don't believe that is the entire reason. Many that have tested are the ones that they are considering breeding this coming breeding season. I tested mine because I wanted to know, as I don't have breeding plans for this coming year. Also wanted to know for the pups that I did have last fall.

What I find interesting (or disconcerting) is that we have not heard about much PRA in Basenji in the last several years… so does these high numbers say that Breeders were not sharing the informtion that there was/is PRA in their Basenjis? Just not having eye exams done on their Basenjis? Or like Fanconi, while we didn't have a DNA test, as a breed we did pretty good job of "guessing"? I hate the thought that it could be just not sharing the information......

[DebraDownSouth]

Pat, I am not in the circles that would get info, but with those high numbers and YOU not hearing, it makes me really concerned people are pretending and no testing or not telling. it is sort of like Cavalier breeders who told buyers their dogs had NO history of heart problems, then you find out they bred early and stopped breeding AND testing before the dogs were even 5 (typically they find MVD in HALF of all Cavaliers by the age of five). Not testing isn't the same as not having issues. So I knew this breeder who neutered all her dogs, 8 generations into the breed, and bought new dogs out of, you know I don't now remember where she imported from– because THEIR DOGS didn't have the high rates. Guess what? They did. They just weren't testing.

As a side note, it was the main reason we didn't get one for Leora to show, and how we ended up with Basenjis. Let's be honest, basenjis are a much better fit.

Many of us have the same thoughts due to the high Carrier numbers for this one type of PRA….

Is this a test I should have for Ava at one year?

You can do it anytime, like Fanconi DNA, it is just a cheek swab that you order from OFA.

[ownedbyspencer]

Thanks for letting me know! I had no idea it was a cheek swab. I suppose I should have the Fanconi test for Ava, too, even though she should be, at worst, a carrier,

Never hurts to that the tests done even if Clear or Carrier by parentage for Fanconi, the more data the better. And for the PRA test, not enough data yet to know if could be Clear/Carrier or Affected by parentage. I forget now what her breeding is/

I must admit, I am on my 10th basenji now, and for those that finished in the ring, or were strickly pets, I only did an initial eye test vs a yearly in the 80's and 90s. The importance of testing really was not stressed by the breeders of my first 3 dogs, nor was it widely publicized that yearly testing for pets should be done. It is never mentioned at a vet visit, wish vets would educate owners on eye testing.

I would bet that many breeders do not know the current eye status of the dogs that went to pet homes. Many dogs get around quite well with fading eyesight and the owners may not even realize they have an issue.

So very true Lisa… I even know breeders that had necropsy's done to find out why a dog passed on, only to be told by the Vet that the dog was blind from PRA and most likely had been for a number of years. They had no clue. While I ask that my puppy owners do an eye exam at 1yr and if no problems, every two years till age 10, every year after 10. Some do, some do not.... And your right about regular Vets, they rarely if ever talk about eye exams from a certified Vet in that field. My ears "prick" when I hear people talk about losing or poor eye sight at night, which can indicate the beginning of PRA = night blindness.

Her father is cleared and her mother is a probable carrier, so Ava has a 50/50 of being either a clear or carrier, but not AFS. The Fanconi test would be a formality, IIRC, and I'm going to do it because I'd like to know. IDT either parent has had the PRA test yet.

Great news

[etzbseder]

How long did you all have to wait for the test results?

[tanza]

Depends… on average 2 to 3 weeks

So glad to hear this about Elliot. Hope he's doing well!
