Novel Genetic Variants Discovered in Two Studies of Inherited Disease in Finnish Dog Breeds – Business Wire

VANCOUVER, Wash.--(BUSINESS WIRE)--Wisdom Health Genetics, the world leader in pet genetics and maker of the WISDOM PANEL dog DNA test, announced the publication of two studies in Human Genetics conducted in partnership with the University of Helsinki.

Both studies discovered genetic variants related to disease in dog breeds of Finnish origin: the first study identifies a variant associated with an endocrine disease in Karelian Bear Dogs, and the second identifies a variant associated with an eye disease in Lapponian Herders.

By analyzing genetic samples including those from the Wisdom Health Genetics database, our researchers and Professor Hannes Lohis team at the University of Helsinki were able to identify genetic variants associated with two inherited diseases found in Finnish dog breeds, said Jonas Donner, Ph.D., Discovery Manager at Wisdom Health Genetics. We are thrilled that we could aid in these discoveries, both of which have practical implications for humans and dogs. These findings will inform the development of genetic tests for the conditions, thus improving veterinary diagnostics and breeding plans, and also help further our understanding of similar conditions in humans.

The first study, Intronic variant in POU1F1 associated with canine pituitary dwarfism, established a novel canine model for endocrine dysfunction known as combined pituitary hormone deficiency (CPHD). Through a combination of genome-wide association and next-generation sequencing studies, researchers identified a candidate gene (POU1F1) containing a disease-predisposing genetic variant present in the dogs with CPHD.

Thirty genes, many of which are regulatory genes affecting pituitary development, have been linked to human hereditary hypopituitarism. Impairment occurs not only in humans but also in mice and dogs. This is only the second and thus very important new dog model for human pituitary disease, said Professor Lohi about the discovery in the Universitys news release about the CPHD publication.

In a second study, A missense variant in IFT122 associated with a canine model of retinitis pigmentosa, researchers identified a recessive genetic variant (IFT122) as the likely cause of progressive retinal atrophy (PRA) in Lapponian Herders. The IFT122 gene has not previously been linked to retinal degeneration in mammals, thus establishing a new model to examine the role of IFT122 in degenerative eye diseases in both humans and dogs alike.

Gene discovery is important because genetic testing can now easily distinguish retinal degenerations associated with different genes in breeds, which is important for disease monitoring, prognosis, and the development of new therapies, said Maria Kaukonen, DVM, in the Universitys news release announcing the PRA publication. Diagnostics will improve and it will make the work of veterinarians easier.

The discoveries of both studies will contribute to the development of targeted genetic screening for dogs like those found in Wisdom Panel tests to improve breeding practices and personalized veterinary care.

Additionally, both discoveries hold promise for advancing human medicine thanks to the novel clues about disease gene biology they provide, and the newly characterized canine models enabling further studies of the conditions.
