Tay–Sachs disease is inherited in an autosomal recessive pattern. The HEXA gene is located on the long (q) arm of human chromosome 15, between positions 23 and 24. Tay–Sachs disease is an autosomal recessive genetic disorder, meaning that when both parents are carriers, there is a 25% risk of giving birth to an affected child with each ...

The life expectancy in some states has fallen in recent years; for example, Maine's life expectancy in 2010 was 79.1 years, and in 2018 it was 78.7 years. The Washington Post noted in November 2018 that overall life expectancy in the United States was declining although in 2018 life expectancy had a slight increase of 0.1 and bringing it to ...
Enzyme replacement therapy is available to treat mainly Fabry disease and Gaucher disease, and people with these types of sphingolipidoses may live well into adulthood. The other types are generally fatal by age 1 to 5 years for infantile forms, but progression may be mild for juvenile- or adult-onset forms.

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 ...
