Adult Onset Deafness Border Collie (Linkage Association Test)

$75.00 (RRP)



This test is currently offered as 'research only' and results should not to be used for making key breeding decisions.  We are working to try and gather data on Border Collie populations with a key focus on Australian show and working lines. Please Note: The price advertised covers laboratory costs associated with running this test.  Results will be issued with any samples submitted.

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
