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.
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 understanding and preventing all autosomal genetic disorders.
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.

If a safe pharmacological treatment can be developed, one that causes the increased expression of lysosomal sialidase in neurons, a new form of therapy, essentially curing the disease, could be on the horizon. [3] Metabolic therapies under investigation for Late-Onset TSD include treatment with the drug OGT 918 (Zavesca). [4] Gaucher's disease.
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]

The Packers also lost starting center Josh Myers to an apparent leg injury late in the fourth quarter. Myers left the field on a cart as the Eagles held a 22-10 lead.
Symptoms of early infantile GM1 (the most severe subtype, with onset shortly after birth) may include neurodegeneration, seizures, liver enlargement (hepatomegaly), spleen enlargement (splenomegaly), coarsening of facial features, skeletal irregularities, joint stiffness, distended abdomen, muscle weakness, exaggerated startle response to sound, and problems with gait.
