Bruce Cattanach writes: "I regret to announce that efforts to clear Wynsett Jumpin' Jack Flash of cerebellar ataxia by retrospective analysis of his past breeding performance have had to be aborted due to ambiguous findings in a recently reported litter. These findings by no means show that Jack Flash was a carrier but they negate any further attempt to prove otherwise by this method."

"A molecular approach is now the only route to ascertain the genetic status of this dog and his descendants, together with all other at-risk dogs in the breed. Hopefully, Matthew Binns at the Animal Health Trust will shortly have enough material to start this line of investigation."
