General
Disease Name
GM2 Gangliosidosis Type I (B Variant)
Mutation
c967G>A
Test Type
Genetic Disease/Disorder
Details
Gangliosidosis is a rare metabolic disorder in dogs. It is commonly known as storage disease because dogs that suffer from it lack an enzyme in their brain that helps with the breakdown of old molecules which build up in the brain effecting the nervous system. Generalised symptoms can vary greatly between dogs but can include: lack of coordination, depression, behavioral changes, head shaking, mental dullness, seizures, blindness, deafness, developmental delay. Specific to GM2-B: difficulty moving and keeping their balance, vision problems, altered mental status (1 and 2 years)

Gangliosidosis is a lysosomal storage disease caused by beta galactosidase deficiency and characterized by progressive neurological deterioration. It is caused by breed-specific mutations. It is commonly known as storage disease because dogs that suffer from it lack an enzyme in their brain that helps with the breakdown of old molecules which build up in the brain effecting the nervous system. Generalised symptoms can vary greatly between dogs but can include: lack of coordination, depression, behavioral changes, head shaking, mental dullness, seizures, blindness, deafness, developmental delay. Specific to GM2-B: difficulty moving and keeping their balance, vision problems, altered mental status (1 and 2 years)
