Lysosomes are structures within a cell that function in waste disposal and recycling. If the lysosome is dysfunctional it leads to accumulation of waste which can cause the cell to die. Fucidosis is a build-up of fucose in cells that can cause neurologic dysfunction.
FUCA1
Autosomal recessive
Affected dogs typically present with neurological signs including difficulty walking (ataxia), altered behavior, seizures, weight loss, difficulty eating and vision loss. These signs typically present around 1 to 4 years of age.
A veterinarian will conduct a thorough exam, including a review of health history and any clinical signs. Neurological tests, including imaging, may be required for a definitive diagnosis since many other diseases present with similar clinical signs. Genetic testing is necessary to determine if there is an underlying genetic cause, which can assist veterinarians with diagnosis and help breeders identify affected and carrier dogs.
