摘要
GM1 gangliosidosis is a fatal, progressive neurodegenerative lysosomal storage disease caused by mutations of the beta-galactosidase (GLB1) gene. In feline GM1 gangliosidosis, a pathogenic mutation (c.1448G%26gt;C) of the feline GLB1 gene was identified in Siamese and Korat cats previously diagnosed with the disease in the USA and Italy, respectively. The present study demonstrated the same mutation in a Siamese cat that had been diagnosed with GM1 gangliosidosis in Japan in the 1960s. The mutation was confirmed using DNA extracted from stored paraffin-embedded brain tissue by a direct sequencing method and a polymerase chain reaction-restriction fragment length polymorphism assay. This pathogenic mutation seems to have been distributed around the world.
