The differential diagnosis between patients with generalized gangliosidosis and several types of genetic mucopolysaccharidoses can be a problem. In both groups of disorders the lysosomal enzyme β-galactosidase has been shown to be deficient in liver, spleen, kidney, brain and skin.1 2 3 The diagnosis of GM1 gangliosidosis is based on clinical phenotype coupled with a normal concentration of derinatan and heparin sulfate in the urine and the absence of β-galactosidase in the liver.
