Fucosidosis is an inherited lysosomal storage disorder caused by a deficiency of the α-L-fucosidase enzyme. This enzyme is responsible for the removal of fucose sub-units from glycoconjugates. Affected dogs will have impaired central nervous system function, which can manifest as mental and motor deterioration, growth retardation and an increased inclination to recurrent infections. First significant symptoms usually manifest at approximately 12-17 months and severe decline in neurological function set in between 18-23 months of age.
