The livers and spleens from three patients with cerebral GM1-gangliosidosis contained greatly increased concentrations of a mucopolysaccharide tentatively identified as keratan sulfate. The concentration of a very soluble sialomucopolysaccharide was also increased. Concentrations of these compounds were not increased in the viscera of patients with Tay-Sachs disease (GM2-gangliosidosis). GM1-gangliosidosis appears to be a combined cerebral gangliosidosis and visceral mucopolysaccharidosis.
