If an individual is diagnosed with a genetic disorder, it can be replaced with a normal sibling or parent and bred to a mate whose risk of having liability genes is low. Replace the higher-risk parent with a lower-risk offspring that equals or exceeds it in other aspects, and repeat the process.
Genetic tests are extremely useful tools to help manage genetic disorders. Even when there is no test or a known mode of inheritance, much can still be done to reduce the incidence of affected and carrier animals. The use of these guidelines can assist breeders in making objective breeding decisions for genetic-disease management while continuing their breeding lines.
It is distressing when a genetic disorder is con rmed. Veterinarians can make positive and practical genetic counseling recommendations to maintain breed lines and genetic diversity, and improve the overall health of breeds. Each breeder will have their own rate of progress depending on the frequency of the defective gene(s)
in their own breeding animals, and which desirable individuals carry liability genes.
With the increasing availability of genetic tests, there
is increased risk of misusing and misinterpreting them. There is also the propensity to recommend inappropriate and unnecessarily genetic testing, which can diminish our clients’ compliancy. It is our responsibility to understand the proper use and interpretation of
genetic tests to provide appropriate genetic counseling recommendations to our clients.
