LEGEND FOR LABORATORY DIAGNOSED CA STATUS (based on genetic marker/mutationtest and/or brain~tissue histopathology):
[N/N] = Clear
CA: [N/CA] = CARRIER
CA: [CA/CA] = AFFECTED
CA: [N/U] = Undetermined - CA status cannot be determined and is inconclusive.. There is an atypical combination of DNA markers and CA carrier status cannot be excluded with confidence.These horses will be retested.

LEGEND FOR VETERINARY DIAGNOSED CA STATUS (based on clinical signs only):
CA: [AFFECTED]

LEGEND FOR DEFAULT DERIVED CA STATUS IN ACCORDANCE WITH THE BREEDING CHART:
Only owners of horses have the option to submit and publish two default CA derivatives under their own responsibility:
CA: [Clear] by parentage" - for a foal of which both parents are tested CA N/N or Clear
CA: [CARRIER] by default (I)" - for a parent of a CA/CA or AFFECTED foal
CA: [CARRIER] by default (II)" - for a parent of a N/CA or CARRIER foal of which the other parent is CA: N/N or Clear

AUTOSOMAL RECESSIVE BREEDING CHART FOR CA:

Please remember that affected horses are of course also carriers of the defective gene. If an affected horse is used for breeding (which happens), no matter the level of their condition, it will produce 100%carriers, never a CA clear horse and if bred to another CA carrier, 50% of the offspring will be CA Affected !
Affected horses should NEVER be used for breeding with any breed or bloodline to avoid spreading this genetic disorder into other breeds.

PREVENT AFFECTED FOALS. TEST BEFORE YOU BREED !
