This study ruled out two candidate genes as the gene responsible for Fanconi Syndrome (FS) in Basenjis. FS, an inherited disease, is a major health concern for the breed. With this syndrome, the tubules in the kidney, for unknown reasons, fail to do their job of reabsorbing nutrients into the dogs system. Undetected, it will shorten the dogs life. The researchers selected two candidate genes, HNF1 and HNF2, to test to see whether either is responsible for FS in Basenjis. After sequencing the HNF1 gene, they determined that it is not responsible for FS. Repeated attempts to sequence the HNF2 gene proved unsuccessful and were terminated when it became know that mutations in human HNF2 cause diabetes, rather than Fanconi Syndrome.
