OptiGen® grants Paw Print Genetics an exclusive sub-license for use of patents for genetic testing of dogs in the USA and Canada for:

progressive retinal atrophy (PRA-prcd)

Collie eye anomaly (CEA)

Congenital stationary night blindness (CSNB)

Retinal dysplasia/Oculoskeletal dysplasia (RD/OSD)

OptiGen, a New York State-based company and Paw Print Genetics, a Washington State-based company, have decided to settle patent litigation filed by OptiGen in August, 2013. The patents at issue in the case are owned by Cornell University and are licensed to OptiGen for canine genetic testing related to progressive retinal atrophy (PRA-prcd), Collie eye anomaly (CEA), congenital stationary night blindness (CSNB), and Retinal dysplasia/Oculoskeletal dysplasia (RD/OSD).

Both OptiGen and Paw Print Genetics offer inherited disease testing to identify carriers and affected dogs for a variety of different canine genetic conditions. The terms of the settlement were not disclosed. 

Based on the settlement, Paw Print Genetics now holds the exclusive North American sublicense from OptiGen for PRA-prcd, CEA, CSNB and RD/OSD testing in the U.S. and Canada. With the sublicense in place, the Orthopedic Foundation for Animal has agreed to allow registry of these tests performed by Paw Print Genetics.

Paw Print Genetics Completes Study on Rare Dog Breed, Drentsche Patrijshond

Paw Print Genetics Completes Study on Rare Dog Breed, Drentsche Patrijshond

Paw Print Genetics announces publication of their investigation of genetic diseases in a rare dog breed known as the Drentsche patrijshond (Drent) or Dutch partridge dog. In collaboration with the Drentsche Patrijshond Club of North America, the Spokane-based company studied 13 Drents for 142 different mutations known to occur in domestic dogs.  In this study, two mutations were identified: three dogs were carriers for hyperuricosuria, a condition that can cause bladder stone formation and four dogs were carriers for von Willebrand disease, type 1. In addition, three dogs were found to be at-risk for von Willebrand disease, and may have mild to moderate signs of disease including easy bruising, nose bleeds or bleeding after losing their juvenile teeth, and prolonged bleeding after surgery or trauma.

The study, published in the current issue of the journal Veterinary Record Case Reports, highlights the need to identify genetic risk factors for rare breeds.  Common breeds, such as Labrador retrievers, have many disorders known to occur because popular breeds are investigated more frequently.  “Because all breeds are susceptible to genetic disease, rare breeds, such as the Drents, have fewer numbers of available breeding dogs and are therefore more susceptible to inherited conditions simply because of population constraints”, said Lisa G Shaffer, PhD, CEO of Paw Print Genetics and the lead scientist on the study.

“Identifying breed-specific genetic risks is crucial for avoiding these conditions in future generations of our breed”, said Brian O’Connor, President of the Drentsche Patrijshond Club of North America, “we can now use this information in our breeding practices to produce healthier dogs in the future.”

Paw Print Genetics Announces Listing for Exercise-induced Collapse by the Orthopedic Foundation for Animals

Paw Print Genetics, a division of Genetic Veterinary Sciences, Inc. is pleased to announce that its customers may request certificates for their dogs from the Orthopedic Foundation for Animals for canine Exercise-induced Collapse (EIC). EIC is a genetic disorder typically associated with Labrador retrievers but can be observed in other breeds. Dogs who suffer from EIC usually develop signs of an episode 5 to 15 minutes after initiation of strenuous exercise. Dogs will lose coordination of their hind legs and in some cases, their entire body. Dogs usually fully recover within 30 minutes and can live relatively normal lives as house pets.

Following the recent decision by the U.S. District Court of Minnesota invalidating the EIC patent, customers can request certificates from OFA for testing performed at Paw Print Genetics. Paw Print Genetics has a number of tests for which certificates can be issued from OFA and is proud that EIC can now be certified for a number of different breeds. For questions concerning a test's eligibility to be certified by the OFA, please contact the laboratory at or 509-483-5950.
