Thank you for that - Without his full name, I have added him to the database as Harmony 'Simba'. I can easily change it. And his date of birth would also help ! When I re-upload the database later today or tomorrow, his details will be there and you can trace the Basenjis behind him who have been tested.
Both his parents are AKC registered but unless they were DNA tested under aliases (not their registered names) they have NOT been tested for Fanconi or PRA.
Most recent in Simba's pedigree to have been tested is Grandsire Harmony's Ramses The Great who tested as 'carrier of Fanconi.' Of his 8 Great-grand parents - 5 were tested. One was a carrier and 4 were clear/normal.
I really do recommend that you check Simba for Fanconi. If he is a carrier, he won't develop the disease but it is always best to know for sure. [www.ofa.org](link url).
