Screening Scheme Description

DNA test - LSD
Lysosomal Storage Disease

Details about the disease

LSD is an inherited metabolic disorder that leads to the dysfunction of lysosomes, which are essential for processing unwanted material to useful substances that cells in the body can use. This causes a build-up of unwanted material and cells losing their function.

Clinical signs

Clinical signs in affected dogs include staggering, uncoordinated gait, involuntary eye movements and behavioural changes, such as aggression. The age of onset ranges from 3 months to 4 years or more, and the condition is progressive and may eventually lead to euthanasia.

How it is 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.
