GM1-gangliosidosis is seen in inbred Friesian calves and is due to a generalised metabolic deficiency in beta-galactosidase and beta-glucuronidase.
Clinical signs become evident during the first week of life and include visual disturbances, depression, swaying of the hindquarters, reluctance to move, and stiffness. Death occurs in 6 – 8 months. This disease is relentlessly progressive, characterised by lysosomal hypertrophy with ultrastructural inclusions occur in neurons, endothelial and other cells.
Definitive diagnosis requires biochemical identification of the storage product and enzyme deficiency.
Because most affected cattle deteriorate over time, euthanasia is usually required.
