Canine Hemophilia B

Canine Hemophilia B is a sex-linked bleeding disorder in canines caused by the absence of functional coagulation factor IX. It is an X-linked recessive disorder, which means that male dogs are either affected or clear of the disease. They cannot be an unaffected carrier. A female, on the other hand, can be affected, clear, or a carrier, but will show no, or far less severe involvement. Symptoms include bloody diarrhea, bleeding under the skin, lameness, respiratory difficulties due to bleeding into the chest and airways, paralysis, and even death due to bleeding into the brain and spinal cord. While gene transfer therapy has been proposed as a possibility for treatment of Hemophilia B, current treatment methods require the infusion of factor IX-rich plasma concentrates in response to bleeding.

Although distinct genetic mutations responsible for canine hemophilia B have been discovered for Airedales, Bull Terriers, Lhasa Apsos, Labrador Retrievers, German Wirehair Pointers, and mixed breeds, ongoing studies suggest that there may be more than one mutation responsible for hemophilia B within a given breed.
