General information
Gangliosidosis (GM2 Type II) 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. This buildup leads to worsening neurological damage and severe symptoms over time. Here we test for an autosomal recessive mutation in HEXB in all cat breeds.
Clinical features
Cats affected with GM2 show progressive neuromuscular dysfunction and impaired growth from an early age. Affected kittens have head tremors at the beginning followed by impaired coordination of leg movements which eventually lead to paralysis.
