@eva:
What I am saying is the current test we have is a linked marker test. It is a very valuable first step and is the result of many hours of research. It is not a direct test as the gene that actually carries fanconi has yet to be identified. Responsible and Reputable breeders and owners will do their part by first having their dogs tested. Then since fanconi is a late onset disease should continue to strip test their dogs regardless of the results they receive for several years and report any inconsistent results so those dogs DNA can be further studied and hopefully bring the researchers closer to problem gene. Sir we are only 3 years into this portion of the battle. There are many dogs who are way younger than the typical age of onset and errors are being reported. There are carriers that have developed fanconi, there are puppies being tested affected from clear parents. There are old dogs that tested affected that have never displayed the disease.
What puppies from Clear Parents are testing affected? Not in data that I have seen? And puppies that are testing affected, have the sire and dam's been retested? And is there any questions about their parentage? The two that I know (puppies testing affected), one was from an admitted sample mix up taken at the 2007 BCOA National when blood was still being used and there were a number of dogs that had to be retested from that time. The other that I know of, turns out there was a question on if the sire/dam were really the parents of that puppy.
While I do not disagree with your about strip testing and that this is a linkage test and as you point out has only been available for coming close to 4yrs so the data is still being collected.
