Glad you know what it is and are able to treat him, im sure he will be better soon!!!
Tilly's Fanconi Test Results
-
Im sorry to hear your Tilly has come back as affected
-
On the OFA site you can sort pretty much any of the fields. So I would guess that UK registration numbers are unique, like AKC registration numbers? So you could sort the list and look that way, provided that people are using the correct registration numbers.
-
renaultf1 - I mean Basenjis in general!
Tanza - I respect what you say. Re gene pool and major problem in the UK- I was only quoting Dr Gonto in reply to a question asked of him. I recall he said he'd advised on 11 over several years.
As Elscodobermann said, until every breeder tests we don't know of how many affected dogs we have here.
I'm not sure of present testing but some people did test before the latest Gary Johnston linked marker. I can only recall a few having been suspected of having developed Fanconi. Those that now have their dogs tested are open about it but on the whole people here are not. I queried with OFA how long a line could just breed carriers. I have only bred for approx 30 years but I have carried on the lines of a breeder who started in the very early 40s - I do know that Fanconi was not diagnosed in her lines nor in mine. Not to say there couldn't have been carriers but statistically, I would have thought that at some point the syndrome would have occurred, although I could be wrong!
I should also add that I am not totally qualified to comment because I have not had my dogs tested for the linked marker. As I had bred my last litter (and don't intend to breed again),when the test was made available here, it doesn't seem necessary. Of course if any one decides they want to use my dog I would have him tested first and also his parents.
However because I care desperately about the breed and have devoted my life to it, it is all is of great concern to me. When it is your own dog diagnosed probably affected I do know how tragic it must be and I feel so desperately sorry for any one who it happens to.
We do have other major problems of course, mainly constructional I think.
Incidentally it seems to me that a great percentage of breeders in the USA do test - am I correct? Probably in years to come it will be the same here. Unforunately our KC are not keen to recognise the linked marker test.
Elscodobermann - I've just looked through the WELKS catalogue and of 10 Breeders there, 5 definitely do test and 2 definitely don't - the other 3, I'm not sure whether they do but they might. It's perhaps not as bad as one might think. Incidentaly I think Tilly's mother's pedigree does include imported stock but I don't think that's got anything to do with it -after all Fanconi Syndrome arises from a mutant gene - when you go down that road it's non-productive!
Tanza -This subject seems to attract many opinions which does mean that people do care which must be good for the future of our beloveds. -
I totally agree that people do care about the breed and that is a good thing, the fact that we can and do discuss openly is what IMO, makes our breed head and shoulders above many others.
In the US, many, many breeders are testing.. however there are most likely just as many Back Yard breeders, Puppy Mills, and even people that call themselves responsible that are not testing.
I am curious, about you not testing yours? Don't you want to know that status, regardless if you are going to breed anymore or not?
I think that many breeders all over the world started testing due to peer pressure… and found out that they indeed had carriers and/or affecteds. Honestly that was one of the things that many of us hoped for, that through peer pressure people would have to test.
-
I remember when I was new to the breed and had made a statement on an email list that Fanconi had been diagnosed in basenjis all over the world and having a breeder in a foreign country email me to tell me that there were no cases of Fanconi in her country, I was wrong and should learn to keep my mouth shut. Dr Gonto had people contact him from that country with cases, they were ostracized by other breeders in their country and if they made it public they were called liars. Even where the reaction was not as extreme as in that particular case, I do think that there has been something of a code of silence regarding Fanconi so it is hard to judge the incidence unless testing is being done.
-
Tanza - You are right about peer pressure - I have actually seen it here in the last few years - gradually people who at first didn't test followed the example of their fellow breeders and I can see that in the not too distant future the majority will test because they will want to use studs of breeders who insist that the bitch must be tested. In a small country like ours peer pressure is particularly effective.
You ask why I haven't tested my dogs - for several reasons really, but my dogs are fit and healthy and because I know my lines and a great deal of the dogs in them I have no cause to think that my basenjis are affected and so am not worried to that extent. If I thought that there was a possibility of them getting the syndrome and so could be forewarned of the necessity to treat them I would test. There is the possibility that we could have always had carriers through the generations and so if really necessary, as I said, I would do so. There are other quite personal reasons which I can't go into here.
We are very lucky here in that Puppy Farmers, as we call them do not trade in Basenjis as they are a non-commercial breed but do have the problems of irresponsible breeders.
When I re-read my answer as to why I don't test I realise that it could seem a strange answer to you, I hope not any how!!
Ivoss - its a little bit like that here but everyone is getting more relaxed about it now, thank goodness. I actually feared there would be a 'witch hunt' as I've seen that before in our breed about many other things!! There was quite a bit of anger about our Breed Council inviting Dr Gonto over to speak and many just refused to go to listen. Those of us who did go learned a great deal and I have tried to impress on the then 'antis' just how useful and informative his talk was.
Benkura - thank you as well, you have given her a lovely home. -
Personally I do not agree with carriers being used as they will only produce more carriers!
The argument is used that good breed points will be lost but they are often lost any way - no guarantee that they will be passed on! 'Ss' law says they won't!Using ONLY clears is a sure way to limit the already small gene pool and have other issues start to show up in vast numbers. This is a crazy way to think. Having lived with both Fanconi Affects AND blind dogs, I couldn't imagine purposely whittling the gene pool to near nothing.
A carrier bred to a clear will produce carriers AND clears…
*Although I'd love to believe this, it is what we WANT to happen,m but no it does not happen all the time. This should read breeding a carrier to a clear MAY produce clears.
Tanza, I also agree that there is more to worry about than Fanconi which is not a very well researched syndrome in the UK. I strongly feel that the Basenji's kidney function needs research too but being a minority breed I know this will not come about.
I am not sure how much you know about Fanconi Syndrome, or that it has been around for YEARS and YEARS. Research has been going on since the 1970s, so I think that is a pretty damned long time. I know the KC does things way differently than in the States, but I'd think that all the research done over here should be taken pretty seriously over there.
I agree too that the gene pool is limited but interestingly when I asked Steve Gonto why he thought that we do not have a major Fanconi problem here (UK) he replied that it was because our gene pool was smaller!! Fortunately in the UK we do not have a lot of recognised problems but as I look at many of the dog's constructon I foresee some arising in the future.
I can tell you right now there are more than that. I can also tell you that just because he says he's talked to 11 people… does that mean that is all there is? Heck no. I know of multiple people that were VERY put off by his rudeness in emails and will not deal with him in any way because of it. Sure, he knows Fanconi, but tact is not his forte.
Your gene pool may be smaller, but since we know of UK dogs impoted to the US that have produced it and tested as carriers tells us that the gene IS in the UK.I totally disagree with your statement about not having a major Fanconi problem…. I think that UK has just dodged the bullet for years. Look how many that were tested from Europe have come back as Carriers or Affected?... In my opinion it was just a short matter of time before Fanconi exploded in the UK... And I am not so sure that the gene pool is smaller in the UK, but more that there are less Basenjis in general. And have people really talked about Fanconi affected dogs. You know when I got in the breed, I heard over and over from people in Europe, Fanconi is not a problem, same from Aussie breeders.... until the test came out... and then all these dogs started showing up as Carriers and/or Affecteds.
C'mon Pat, if you don't test, you must NOT have it!! :eek:
Tanza - You are right about peer pressure - I have actually seen it here in the last few years - gradually people who at first didn't test followed the example of their fellow breeders and I can see that in the not too distant future the majority will test because they will want to use studs of breeders who insist that the bitch must be tested.

There are other quite personal reasons which I can't go into here.I have found over the past few years that Europeans are coming to the US for dogs as we are doing Fanconi Testing regularly.. and for any dog to have been whelped and tested Affected SINCE the test came about is utterly irresponsible by the breeders, regardless of who they are… unfortunately, it is still happening.
I still believe that until these breeders LIVE with a Fanconi Affected dog, they will not know how serious the issue can be.

*Although I'd love to believe this, it is what we WANT to happen,m but no it does not happen all the time. This should read breeding a carrier to a clear MAY produce clears.
.
Right, of course I should have said "may, or can" produce clears…of course with my luck, the whole litter would be carriers....no, wait....with my luck, the wrong test result would have been given to me, and my clear bitch would actually be a carrier....

Having been in the breed for a 'couple' of years - and also understanding scientific process terminology here is my thought(s).
UK and other European countries have maintained for years that they did not have fanconi, hip dysplasia etc etc (insert breed and insert disease). To disabuse everone of that 'myth' Gonto's once published that he had samples from every country that had basenjis - and all countries had it. He did not divulge names of animals, kennels or people as he had promised confidentiality - but he did say it was beyond the US.
When a scientist makes a statement about "gene pool too small to get it" I believe that is someone interpertation that is their understanding of what they think was said. What was likely said is that "your sample size is too small". which means there are not enough dogs collected to make a blanket statement of the prevalance of the disease.
One thing I have learned with working with my Portuguese Breed and breeders overseas is that they focus on something like "fit for purpose" Those who cannot do what the purpose is don't live (either because of natural result or are eliminated) - so how would you know what disease they carry. I have had tons of breeders tell me that the Podengo has no health issues - well guess what - in the small size they get legg calves PErth just like other small breeds - if they can't hunt rabbits in portugal however - they are killed. End of problem.
Now I'm hearing of some dogs with seizures - thyroid? or something else - who knows no one tests.
BUT I also remember one of the reasons our original gene pool got so small and interrelated in the US was by removing too many dogs from the gene pool with aggressive HA and PRA testing. I think it's smart to know - and smart to use that knowledge to improve the breeds health AND diverstiy.
-
My litter was carrier to clear (which was before testing was available) I had three carriers and one clear, I was unlucky, I know of a litter bred this year carrier to clear that had three clear and one carrier, one dog and two bitches, we can't afford to completely discount carriers (obviously only to clear), but I do believe that all of the pups should be tested and the prospective owners told of the results, now that the test is so much simpler and quicker it is much easier to do.
-
Khanis - I respect what you say and you do make a good points. I'm sorry that I mentioned my opinion about carriers because it has obviously caused you upset. Yes I have read a great deal abut Fanconi but certainly am always willing to learn. - I have learnt something more on this forum. I do know though that Fanconi syndrome arises from a mutant gene and so could arise at any time. I'm not a geneticist either so have only general understanding of the transmission of genes but have read quite a bit and researched linked marker tests too.
UK KC does take note of research from all over the world - after all science is science in whatever country. Very little research has been done over here on Fanconi Syndrome and so they obviously rely on that done in other countries.
Yes I do know that Fanconi has been around for a long time; in the past the available test was used by some breeders and owners here but now that the current test is available many more use it - I looked through a recent show catalogue and out of 10 breeders only three definitely don't (yet).dmcarty - I quoted exactly what Dr Gonto said and didn't paraphrase. I am interested in your comments on Podengos, a breed fairly new to this country. I have been to several Podengo seminars and two of Portugal's top breeders told us that Perthes disease was one of their health worries so I don't think they are hiding issues here. In my experience too Basenji breeders are aware of health problems but there is not enough open discussion on health; maybe because some people just can't discuss without getting heated. Basenjis have never been bred extensively here and in general are not considered a commercial breed. In the early days there was quite a bit of culling too as they were trying to eliminate what they considered was not correct.
-
Before the linkage test, there was no other test? Other then monthly strip testing? So not sure what other test you might be referring to.
I may be misunderstanding your reference to "mutant" gene and that is can show up any time? It has been determined that it is a recessive gene, so it doesn't just show up. Any time you breed a clear, depending on if you use a Carrier or Affected, you will maybe get Carriers (and all Carriers if you use an Affected)… but never Affecteds, as we understand the test at this time.
-
Actually Pat - remember the old urine tests that Dr Brown and Dr Bovee were doing - that proved by the way to be not quite accurate. Gee I remember collecting urine and putting it on ice and sending it off Fed Ex hoping that the cooler packs lasted until the sample got where it needed to be.
Patty - I sent you a private message on Podengos you can access once it is approved by clicking on your welcome at the upper right of your screen
-
Thank Diane…. yes I do remember, but never considered that a test.... as I understood (since it was before my time) they were not even close to accurate.
-
Well it was all we had at the time - although there are some sterling examples of anmals who were considered "clear' via that test (whatever clear was) that turned out to be affected.

That I remember hearing…. with the linkage tests... the results are pretty much in 99% of the tested dogs, what you would expect to see... at least to date... so we are certainly better off then in years prior
-
Everytime we choose not to use a dog diversity is lost in our genepool. We lose so much already due to things like popular sire syndrome it would IMO be catastrophic to the breed to further reduce diversity by eliminating all carriers simply because they are carriers. There are far more issues in the breed than just Fanconi and all bottlenecking for one reason or another will only help to express other issues in the breed like a rise in PRA, HD, Hypothyroidism, or some other condition that may currently be quite rare. It is better for the breed that the gene is eliminated over several generations.
I have been sitting back and reading, and while I do agree that its better for the breed that the gene is eliminated over several generations there are a few things bothering me.
Popular Sire Syndrome came about because of what?
It has been asserted that there is a rise in PRA, HD(hip displasia unless I am misunderstanding), and Hypothyroidism. Aren't all of those that have been mentioned genetic? If so, and we understand that these issues are genetic, then why are they on the rise?
I know what I believe the obvious answer to be to the above questions and it does concern me. I also know if we are aware of these other issues and steps have been taken to identify and test for these conditions and they are still on the rise then what hope do we have for any better results in regard to Fanconi?

Anyway…................Hope Tilly is doing well and is enjoying the extra attention that these special Basenjis deserve. I will be thinking of Tilly often.

It has been asserted that there is a rise in PRA, HD(hip displasia unless I am misunderstanding), and Hypothyroidism. Aren't all of those that have been mentioned genetic? If so, and we understand that these issues are genetic, then why are they on the rise?
They may be genetic diseases, but they aren't so clear cut as our fanconi test is. The fanconi is caused by one gene, and it's a simple recessive, which means that the dog must get the bad gene from both parents in order to get the disease. And because of this simpleness, the test can clearly tell you what your dog's status is at an early age and how to work around that for breeding purposes.
HD is different, for example. There is no genetic test for displaysia. And it is believed to involve several genes. Makes it much more difficult to work with. You can xray the hips and "grade" them to see if they are displastic or not. But you can't tell exactly how that will affect offspring of the dog. A dog with excellent hips can produce any kind of hips, and there have been cases of dysplastic dogs producing excellent hips!
There is no genetic test for thyroid either, and some breeds have one for PRA, but most (including Basenjis) do not. So we have to do our best to test before we breed and only use those who have the best possible test results. But most of those tests aren't so exact like the fanconi test. And since many of these things don't show up in a young dog, it helps to wait until the dogs are mature to breed in most cases.
Also keep in mind more and more things are showing up because more and more dogs are getting tested these days. Once you test, now you can see it's there. But when you don't test, you basically ignore the possiblity that there might be something there. For example, just because a dog didn't die from thyroid problems, doesn't mean it didn't have them to one extent or another and may or may not have passed it on to offspring generation after generation. Then all of a sudden you start testing and surprise, dogs are HT!
And of course this is all assuming that breeders put health as a top priority in breeding. But as you I am sure are thinking, unfortunately there are many that just care about other things. sigh
-
I understand that Hips can only really be judged by X-ray. I guess the only way and its probably not exact is to know the history of the line and keep records to see if Hip Displasia presents itself in any of the past breedings to know what may or may not happen in a future one. Still from what you are saying, I get there is no sure way to really determine if HD is a possibility or not. Please correct me if I am wrong.
I do find it very hard to accept that there is no real way to test for Thyroid. As much research as has been done on this(at least were humans are concerned) one would think we would have a better handle on this. I do know animals are used in research and I would have hoped by now with all the scientific advances we have had we could have identified a way to test for this.
Its amazing that we have reached a level in stem cell research where we can clone a dog, a farm animal, and possibly more, but we still remain infants in regard to identifying the components that would allow us to have some insight into genetic disorders.
Issues like these make me want to reinforce something I said in the post where I talked about neutering our Basenji. I would encourage everyone to pull a yearly blood panel on their Basenji. At least that way, your Vet has a road map for your dog and also it give you and your Vet a heads up where you might catch an inkling or indication of a problem in its early stages. I know I will include a Thyroid Test for our Basenji just because of what I have read about possible Thyroid issues on this forum.
Although I am not a Breeder and never plan to become one, I do love the breed from my brief exposure to Basenji's and I wish to do all I personally can to help insure I have a healthy dog and provide a good home for the one I currently have and the possible one(or ones) I will have in the future.
