About This Disease

Liver shunts, (portosystemic shunts) are defects in the portal vein which connects the liver to the rest of the circulatory system. This defect affects many breeds, including Bernese Mountain Dogs. The liver removes toxins such as ammonia from the blood; shunts prevent blood from reaching the liver. Consequently, the liver does not develop properly as the puppy grows. In addition, toxins such as ammonia bypass the liver and reach the body′s blood circulation, including the brain. Neurological symptoms begin in the first year of life and without treatment the condition is fatal. Surgery is the only long term treatment, but is not always successful. Work by researchers at Utrecht University and others has shown that portosystemic shunts are most likely inherited.

About This Research Project

Dr. Jan Rothuizen at the Utrecht University, Netherlands, is working with the Dutch BMDC to find a genetic marker for portosystemic shunts in BMDs so that breeders can determine whether dogs carry this defective gene.

What is Needed? (if you participate)

To study this disease, the research needs blood from affected dogs, their parents and as many littermates as possible.
