A rare form of this disease, known as Adult-Onset or Late-Onset Tay–Sachs disease, usually has its first symptoms during the 30s or 40s. In contrast to the other forms, late-onset Tay–Sachs disease is usually not fatal as the effects can stop progressing. It is frequently misdiagnosed.
All three disorders are rare in the general population. Tay–Sachs disease has become famous as a public health model because an enzyme assay test for TSD was discovered and developed in the late 1960s and early 1970s, providing one of the first "mass screening" tools in medical genetics. It became a research and public health model for ...
Tay–Sachs disease was the first of these disorders to be described, in 1881, followed by Gaucher disease in 1882. In the late 1950s and early 1960s, de Duve and colleagues, using cell fractionation techniques, cytological studies, and biochemical analyses, identified and characterized the lysosome as a cellular organelle responsible for ...
Tay–Sachs disease. In addition to its classic infantile form, Tay Sachs disease may present in juvenile or adult onset forms, often as the result of compound heterozygosity between two alleles, one that causes the classic infantile disease in homozygotes and another that allows some residual HEXA enzyme activity.

Generally, the other types are fatal by age 1 to 5 years for infantile forms, but progression may be mild for juvenile-onset or adult-onset forms. [citation needed] Alternatively, some of the sphingolipidoses may be classified into either GM1 gangliosidoses or GM2 gangliosidoses. Tay–Sachs disease belongs to the latter. [citation needed]

Onset of adult GM1 is typically in adolescence or adulthood and is the slowest progressing of the subtypes. [ citation needed ] Symptoms include muscle atrophy, neurological complications that are less severe and progress at a slower rate than in other forms of the disorder, corneal clouding in some patients, and dystonia (sustained muscle ...
