DNA test - HCA (Hereditary cerebellar ataxia)

Details about the disease

Hereditary cerebellar ataxia (HCA) is a condition that affects the way a dog moves. Affected dogs may show signs as early as 12 weeks of age. The condition is likely to progress and get worse as the dog gets older. Affected dogs are often euthanised due to welfare concerns.

Clinical signs

Affected dogs may have uncoordinated movements and head tremors.

How is it inherited?

The disease is described as an autosomal-recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
