Test Overview:

Genetic testing of breeding cats is strongly recommended to identify carriers. Avoid breeding carrier × carrier to prevent producing affected kittens. Carrier × clear (non-carrier) matings are acceptable; 50% of offspring become carriers, 50% clear. Affected cats should not be bred. Gradual reduction of mutation frequency through selective breeding while preserving breed genetic diversity.
