What breeds are most prone to cerebellar cortical degeneration?

Cerebellar Cortical Degeneration primarily affects Vizslas. The condition is autosomal recessive, caused by a mutation in the SNX14 gene. DNA testing for the SNX14 gene is available and gives a definitive answer. Affected dogs need two copies of the mutation. Carriers (one copy) are clinically normal. Never breed two carriers — Carrier × Clear pairings produce no affected puppies. Test all breeding stock and share results with your breed club.
