Lysosomal storage disease is a group of neurometabolic diseases mainly occurring in infancy and childhood. Clinical manifestations are not always uniform for a single disease with mutations in the same gene. Clinical subtypes have been proposed for many lysosomal diseases. At present, the molecular and metabolic basis of each phenotypic expression is not clear, although common mutations have been found for specific clinical forms in some diseases. In this article, some results are reviewed on hereditary β-galactosidase deficiency disorders, β-galactosidosis (GM1-gangliosidosis and Morquio B disease) and galactosialidosis. In both diseases, gene mutations causing various phenotypic expressions have been identified, and clear genotype-phenotype correlations have been established. The pathogenesis, new diagnostic procedures, and possible molecular treatment in some cases are discussed.
