Galactosialidosis (β‐Galactosidase ‐ Neuraminidase Deficiency): A New Hereditary Metabolic Disease with Abnormal Degradation of Enzyme Molecules

Abstract
Galactosialidosis is a recently established heredodegenerative disease occurring in adults, characterized by cerebellar ataxia, myoclonus, cherry‐red spots, angiokeratoma and deficiencies of two lysosomal enzymes, β‐galactosidase and neuraminidase. Results of recent investigations are briefly reviewed and the molecular basis of this new disease is discussed.
