Gangliosidosis 1 (GM1)

Gangliosidosis GM1is a hereditary disease that can be tested with a DNA test. Gangliosidosis is an inherited error of lipid metabolism, also known as a 'lysosomal storage disease'. An autosomal recessively inherited deficiency of acid β-galactosidase activity affects brain and multiple systemic organs.GM1- gangliosidosis in Siberian Husky affects brain, causing progressive neurological impairment. Affected dogs suffer from paralysis of the extremities and spasticity of the muscles. At the age of about 8 months, most dogs die of this disease.
