Some Common Genetic Disorders in Cats

0 Comments Posted by islandtreesadmin in Uncategorized on Tuesday, June 14th, 2016.

Pedigreed cats have several hereditary disorders which require screening and counseling. Thirty-eight percent of all Persian and Himalayan cats have an autosomal dominant polycystic kidney disease. Many of these cats develop kidney failure, while some only develop isolated cysts that do not impair normal kidney function. A genetic test for this disorder is now available.

The Maine Coon cat breed has a dominantly inherited hypertrophic cardiomyopathy, as well as a high incidence of hip dysplasia. Both disorders are commonly identified in this breed. Renal amyloidosis is a hereditary disorder found in the Abyssinian breed.


Other frequently encountered genetic disorders in dogs and cats include: deafness, porto-systemic shunts, various types of bladder stones, elbow dysplasia, patella luxation, and Legg-Perthes disease. There are no breeding recommendations that fit every situation. There are, however, guidelines to preserve breeding lines and genetic diversity while reducing the risk of producing carrier or affected individuals.

Protocols for genetic counseling and breeding management of genetic disorders can be based on the known mode of inheritance and the availability of genetic tests. Contact your veterinarian at Island Trees Veterinary Hospital for recommendations.
