Overview
A number of tests are available for the Russian Black Terrier. Two or more of these tests purchased as part of this bundle will be discounted.
- Hyperuricosuria associated with the SLC2A9 gene
- Multi-Drug Resistance associated with the ABCB1 gene
- Progressive Retinal Atrophy associated with the PRCD gene
Hyperuricosuria
Dogs with hyperuricosuria most commonly present with symptoms of recurrent urinary tract inflammation, which include frequent urination, blood in the urine, and straining to urinate. They may also have loss of appetite, lethargy, weakness, vomiting and pain. Urinary stones in the bladder can cause urinary tract infections or more seriously, blockage of the Urethra. Both male and female dogs can be affected, but due to differences in their anatomy obstruction of urine flow is more common in males. Although an x-ray can be used to exclude other types of stones, urate stones cannot typically be seen using x-rays and must be evaluated by ultrasound.
Multi-Drug Resistance
In certain breeds a mutation on the ABCB1 gene, which encodes the MDR1 protein (which stands for Multi Drug Resistance 1) can cause animals that carry the mutation to be particularly sensitive to certain drugs. The variant was first detected in a subpopulation of dogs that were highly sensitive to Ivermectin-induced neurotoxicity. The variant on the ABCB1 gene results in the brain being unable to efficiently pump some drugs out, causing a toxic build-up of these drugs in the brain. Dogs subsequently experience and range of symptoms from vomiting and diarrhea to lethargy, seizures, or coma.
Progressive Retinal Atrophy (PRCD)
*Optigen Officially Licensed*
Progressive retinal atrophy (PRA) is the most common form of inherited disease affecting the retina in dogs. Genetically different forms of PRA, caused by mutations in different genes, affect many breeds of dog with each form usually affecting one or a small number of breeds. PRA is characterised by progressive degeneration of the retina at the back of the eye and leads to vision loss and blindness.
Progressive Rod Cone Degeneration (PRCD) is a form of PRA and was one of the first PRAs for which a genetic variant was identified. PRCD is different than most forms of PRA in that the variant has been found in a large number and diverse range of breeds.
