Sandhoff disease is a lysosomal genetic, lipid storage disorder caused by the inherited deficiency to create functional beta-hexosaminidases A and B. [1] [2] These catabolic enzymes are needed to degrade the neuronal membrane components, ganglioside GM2, its derivative GA2, the glycolipid globoside in visceral tissues, [1] and some oligosaccharides.
Highly variable, infantile neurovisceral Niemann Pick disease (Type A ASMD) is usually fatal before 3 years of age. Estimasted mortality before adulthood for the Chronic visceral form (type B) is around 15-25%. Many live well into adulthood and may reach a normal lifespan.

Tay–Sachs disease is a rare autosomal recessive genetic disorder that causes a progressive deterioration of nerve cells and of mental and physical abilities that begins around six months of age and usually results in death by the age of four. It is the most common of the GM2 gangliosidoses.
Signs and symptoms of GM2-gangliosidosis, AB variant are identical with those of infantile Tay–Sachs disease, except that enzyme assay testing shows normal levels of hexosaminidase A. [2] Infantile Sandhoff disease has similar symptoms and prognosis, except that there is deficiency of both hexosaminidase A and hexosaminidase B. Infants with this disorder typically appear normal until the age ...
