I agree that it is very important that any dog from untested parents should be tested using the DNA Marker Test for Fanconi.
I just also want everyone to know that there are other heritable diseases in basenjis that can also effect their quality of life and can lead to disasterous outcomes for the dog if not diagnosed and treated. Untreated hypothyroidism can lead to seizures, cartiledge breakdown, and other preventable problems. Blind dogs often become confused and scared when furniture is suddenly rearranged and they can not navigate areas that were once familiar to them.
We have a marker test for Fanconi because of dedicated breeders and owners. It is also because of the willingness of so many in the basenji community who submitted not only blood samples for DNA extraction but also detailed health surveys and health records for the dogs they submitted that researchers are interested in working with us to find markers for other diseases. The more each of us does to collect information on our own dogs and keep the information in the Canine Phenome Project up to date the closer we can come to having markers for the other diseases found in the breed.
