Gangliosidosis (GM2 Type I) – Japanese Chin
Code: H361
Short description
Gangliosidosis (GM2 Type I) is a fatal, progressive neurodegenerative disease caused by mutations in the HEXA and HEXB genes.
General information
Gangliosidosis (GM2 Type I) is a fatal, progressive neurodegenerative disease caused by mutations in the HEXA and HEXB genes. These mutations lead to a deficiency of an enzyme that is crucial for breaking down ganglioside GM2 in cells, especially in the brain. As a result, gangliosides build up in nerve cells, causing their dysfunction and death. This buildup leads to worsening neurological damage and severe symptoms over time. Here we test for an autosomal recessive mutation in HEXA in the Japanese Chin dog (also known as Japanese Spaniël).

Clinical features
Dogs affected with Gangliosidosis GM2 type 1 can show a variety of symptoms including lack of coordination, depression, behavioral changes, head shaking, mental dullness, seizures, blindness, deafness, developmental delay. The disease is progressive and is likely to lead to death within several months. Euthanasia on humane grounds is likely to be considered.
