WebTay-Sachs disease is one of the few neurodegenerative diseases of known causes. It results from mutations of the HEXA gene encoding the alpha subunit of beta-hexosaminidase, producing a destructive ganglioside accumulation in lysosomes, principally in neurons. With the determination of the protein sequence of the alpha and … WebTay–Sachs disease is an autosomal recessive disease characterized by the inability to degrade ganglioside GM2 owing to a deficiency of N-acetyl-galactosaminidase (hexosaminidase). Ganglioside GM2 is abundant in cells of the central nervous system and accumulates within the lysosomes of neurons and macrophages.
