Tay-Sachs disease market is expected to reach USD 710 million by 2034

Tay-Sachs disease is a rare, inherited lysosomal storage disorder caused by mutations in the HEXA gene, leading to deficiency of the enzyme beta-hexosaminidase A. This results in the accumulation of GM2 ganglioside in nerve cells, progressively damaging the central nervous system. Tay-Sachs is most common in infants, but juvenile and adult-onset forms also exist.

The condition is devastating, with no current cure, and most infants with the acute form do not survive beyond early childhood. However, growing investments in gene therapy, enzyme replacement therapy, and advanced diagnostic screening are fueling hope for disease-modifying treatments. Government support for rare diseases, along with orphan drug incentives, is driving strong research activity.
