The gangliosidoses.


The gangliosidoses are hereditary diseases with a recessive mode of inheritance and are caused by a genetically induced enzymatic block, which results in the accumulation of gangliosides in various tissues of the body, mainly in the brain. Although Tay-Sachs disease, the most commonly occurring of the gangliosidoses, has been known for nearly 100 years, additional variants of ganglioside "storage" disorders have been discovered during the past 15 years. Considerable progress in the knowledge of these disorders has been made with the advent of electron microscopy and with the elaboration of new biochemical and enzyme-chemical techniques. At the present the gangliosidoses are not amenable to therapy. Therefore the foreseeable future the pragmatic approach involves identification of the high-risk pregnancy and antenatal diagnosis.
