Hi Pedro,
Check out this page that I made, it may clear things up for you:
http://khanisbasenjis.com/fanconi.htmlI am not sure why you said IND between carrier and affected, as the IND is between a clear and a carrier. It just means that some of the genes are kind of weird and they aren't showing to be clear. It has to do with the DNA, not the test, and since this is a linkage test that is the best we can do for now.
Kathy,
At the 2007 Nationals Dr Johnson did say that while there have not been any dogs that tested IND between Carrier and Affected, he did say because this is not the direct test yet, it could happen, just has not. Lisa was correct in posting about that, I had totally forgotten him saying that when asked.
