Briard DNA screening

Important information about the DNA Test Control Scheme - CSNB

The following breeding control scheme has been agreed by representatives of the Briard Clubs and the Kennel Club, effective from 01 January 2013 :

1. All Briards used for breeding should be either proven hereditarily clear of CSNB; or have a CSNB DNA test before they are used for breeding.

2. Identified carriers may be used for breeding providing that they are only mated to a Briard that is either hereditarily clear or DNA tested clear of CSNB. Carriers should not be mated to carriers and the Kennel Club will refuse to register any progeny resulting from such a mating.

3. All of the offspring of a carrier mated to a clear should be clearly identified, DNA tested and registered as either tested clear or a carrier.

Distinguishing between clear, carrier and affected dogs

Clear dogs have no copies of the mutant gene responsible for the condition and will neither develop the condition nor pass the gene on to their offspring.

Carrier dogs have one copy of the normal gene and one copy of the mutant gene; they will not develop the condition, but will pass a mutant gene on to approximately half of their offspring.

Affected dogs have two copies of the mutant gene that causes the condition and will develop the disease.
