Lysosomal storage disease (LSD)is a hereditary disease which can be tested with a DNA test. Lysosomal storage disease (LSD) is an autosomal recessive lysosomal storage hereditary disease. Defects in the cell’s degradation process cause various cellular materials to accumulate within the cells. This waste material affects nerve cell function, causing a progressive neurodegenerative disease. Progressive cerebellar ataxia is the main symptom in affected dogs, but episodic nystagmus (involuntary eye movement) can also manifest. Behavioral changes such as increased aggression or depression worsen as the disease progresses. First signs appear between 4 months and 4 years of age. Depending on howthis hereditary disease develops, life expectancy can be mildly or severely affected.

Inheritance: autosomal recessive - read more

Mutation: ATG4D gene

Genetic test: The method used for genetic testing is extremely accurate and allows complete differentiation between affected animals, carriers and healthy dogs. DNA testing can be done at any age.
