  • Descrição: Introduction: Lysosomal storage disease is caused by the deficiency of a single hydrolase (lysosomal enzymes). GM2 gangliosidoses are autosomal recessive disorders caused by deficiency of β-hexosaminidase and Tay-Sachs disease (TSD) is one of its three forms.Objective: To perform a review of the state of the art on TSD describing its definition, epidemiology, etiology, physiopathology, clinical manifestations and news in diagnosis and treatment.Materials and methods: A literature search was carried out in PubMed using the MeSH terms “Tay-Sachs Disease”.Results: 1 233 results were retrieved in total, of which 53 articles were selected. TSD is caused by the deficiency of the lysosomal enzyme β-hexosaminidase A (HexA), and is characterized by neurodevelopmental regression, hypotonia, hyperacusis and cherry-red spots in the macula. Research on molecular pathogenesis and the development of possible treatments has been limited, consequently there is no treatment established to date.Conclusion: TSD is an autosomal recessive neurodegenerative disorder. Death usually occurs before the age of five. More research and studies on this type of gangliosidosis are needed in order to find an adequate treatment.
