Adult Onset Deafness Border Collie (Linkage Association Test)



Test Overview:

Domestic dogs can suffer from hearing losses that can have profound impacts on working ability and quality of life. We have identified a type of adult-onset hearing loss in Border Collies that appears to have a genetic cause, with an earlier age of onset (3–5 years) than typically expected for ageing dogs (8–10 years).


Nervous system / Neurologic - Associated with the brain, spinal cord and nerves



Variant Detected:

c.846+5 T>G


Low-Moderate. This disease can cause some discomfort and/or dysfunction in the affected animal. It does not generally affect life expectancy.

Mode of Inheritance:

Complex - Mode Unknown
