Genetic Testing for PLN-Associated Variant Genes

After years of research supported by hundreds of Wheatens and their owners and breeders, Dr. Meryl Littman and Dr. Paula Henthorn at the University of Pennsylvania School of Veterinary Medicine (Penn Vet) identified mutations associated with PLN in two genes. A cheek swab test to determine an individual dog’s DNA status was introduced in May 2012. Read More ➤

Statement on Genetic Testing for PLN-Associated Variant Genes

Responsible Soft Coated Wheaten Terrier breeders and stud dog owners breed for type, temperament, soundness and health. The recent introduction of the test for PLN-associated variant genes gives us an additional tool to use in the health assessment of breeding stock. Using this test should give Wheaten breeders the ability to reduce the incidence of dogs with these variant genes slowly and carefully while still maintaining genetic diversity.

The Soft Coated Wheaten Terrier Club of America, Inc., and the SCWTCA Endowment, Inc., endorse testing for PLN-associated variant genes by breeders and stud dog owners as one tool in the assessment of breeding stock.

We strongly encourage all owners to become familiar with the test and to understand the meaning of the results and their use in breeding. Resources are available in the health section of the SCWTCA website at www.scwtca.org/health. SCWTCA neither requires nor prohibits any form of breeding beyond what is currently in the Code of Ethics.

All Wheaten owners should remember that screening for health goes beyond performing this test. Members of SCWTCA are reminded of the requirements of the Code of Ethics in regard to other testing and breeding requirements.
