@Patty:
I think thatthe majority of our breeders are testing now but there are still some who don't. The few I know intimately who don't test, to my knowledge, have never had a basenji with Fanconi. Not to say that we haven't got Affected dogs but not many because we have so many fewer Basenjis. For years now the Basenji has not been a popular breed here so registrations are relatively low.
This has always been my puzzle because I've never had a basenji affected with Fanoni and nor anything that could have been fanconi but misdiagnosed as something else. When I had my oldies tested (the test hadn't been available while I was still breeding) I was surpirised to find that one was clear and one a carrier. I must have been breeding carriers or clears only for years! I just don't understand how this is so.
To show the difference between the relative size of the UK and the US Basenji population we currently haven't any in Rescue and for several years had none. In recent years we've had as many as 6 but this is quite rare.
I don't know what our registration figures are for 2009 but if you're interested I can check for you.
No different then many in the US that have been breeding for years only to find out with the DNA test that they have just about all Carriers. Luck of the drawl… when you have a recessive gene. And some of the offspring of those dogs came back as Affected, at least one being in Germany. Many other in the UK tested and found Carriers... one that place a pup here in the US that test Affected...
If you are lucky enough in the "luck of the recessive drawl" to have been breeding Carriers to Clears... and then being lucky enough to take a Clear to a Carrier... not at all hard to understand... but without the test, it would have caught up to many pretty quickly.
And the number of Affected?... I would disagree with you... because Dr. Gonto has said many times that there are a number of Affected in the UK, judging by the number of people that have contacted him. And I am not trying to point fingers, just stating fact because everyone that has a Basenji was/is in the same boat. The best news is that we have a test... and looking at the results in the OFA database they ring true. Yes there are a few that could be questionable.... and with any luck we will soon get a direct test. But right now, this is the best we have and it is a hell of a lot better then having nothing before the linkage test came out.
Again.. all IMO
