Gene Therapy Approach Gene therapy is being researched to potentially treat both Tay-Sachs and Sandhoff disease. Gene therapy aims to be a one-time treatment that could slow or stop disease progression by delivering working HEXA and HEXB genes into the cells using a viral vector.Sep 28, 2021
What is the treatment for tay sachs?
Enzyme replacement therapy. Since Tay-Sachs is caused by the lack of the HEX-A enzyme, this treatment seeks to replace the enzyme. So far, several complications have kept this from being effective for Tay-Sachs. Enzyme enhancing therapy. This therapy uses molecules to stabilize enzymes and increase their activity.
What is the cause of Tay-Sachs disease?
A defective gene on chromosome 15 causes Tay-Sachs disease. This defective gene results in the body not making a protein called hexosaminidase A (HEX-A). Without this protein, a molecule called GM2 ganglioside builds up in nerve cells in the brain, destroying these cells.

Symptoms may include muscle weakness, seizures, and recurring respiratory infections. Adult Tay-Sachs, sometimes known as chronic or late onset Tay-Sachs, is the mildest form. Symptoms appear during adolescence or adulthood. People with the adult form of Tay-Sachs disease usually have these symptoms: muscle weakness.

What is tay sachs disease?
What Do We Know About Heredity and Tay-Sachs Disease? Tay-Sachs disease (TSD) is a fatal genetic disorder, most commonly occurring in children, that results in progressive destruction of the nervous system.
What is the cause of Tay-Sachs?
Tay-Sachs is caused by the absence of a vital enzyme called hexosaminidase-A (Hex-A). Without Hex-A, a fatty substance, or lipid, called GM2 ganglioside accumulates abnormally in cells, especially in the nerve cells of the brain.
How old is a baby with Tay-Sachs?
However, a baby with Tay-Sachs disease appears normal until about six months of age when its development slows. By about two years of age, most children experience recurrent seizures and diminishing mental function. The infant gradually regresses, and is eventually unable to crawl, turn over, sit or reach out.
How to identify Tay-Sachs carriers?
A simple blood test can identify Tay-Sachs carriers. Blood samples can be analyzed by either enzyme assay or DNA studies. The enzyme assay is a biochemical test that measures the level of Hex-A in a person's blood. Carriers have less Hex-A in their body fluid and cells than non-carriers.
What is enzyme assay?
The enzyme assay is a biochemical test that measures the level of Hex-A in a person's blood. Carriers have less Hex-A in their body fluid and cells than non-carriers. DNA-based carrier testing looks for specific mutations or changes in the gene that codes for Hex-A.
What is assisted reproductive therapy?
Assisted reproductive therapy is an option for carrier couples who don't want to risk giving birth to a child with Tay-Sachs. This new technique used in conjunction with in-vitro fertilization enables parents who are Tay-Sachs carriers to give birth to healthy babies.
Is bone marrow transplant successful?
Bone marrow transplantation has been attempted also, but to date has not been successful in reversing or slowing damage to the central nervous system in babies with Tay-Sachs. Another avenue of research is gene therapy in which scientists transfer a normal gene into cells to replace an abnormal gene.
What is Tay-Sachs disease?
Tay-Sachs disease belongs to the group of autosomal-recessive lysosomal storage metabolic disorders. This disease is caused by β-hexosaminidase A (HexA) enzyme deficiency due to various mutations in α-subunit gene of this enzyme, resulting in GM2 ganglioside accumulation predominantly in lysosomes of nerve cells. Tay-Sachs disease is characterized by acute neurodegeneration preceded by activated microglia expansion, macrophage and astrocyte activation along with inflammatory mediator production. In most cases, the disease manifests itself during infancy, the “infantile form,” which characterizes the most severe disorders of the nervous system. The juvenile form, the symptoms of which appear in adolescence, and the most rare form with late onset of symptoms in adulthood are also described. The typical features of Tay-Sachs disease are muscle weakness, ataxia, speech, and mental disorders. Clinical symptom severity depends on residual HexA enzymatic activity associated with some mutations. Currently, Tay-Sachs disease treatment is based on symptom relief and, in case of the late-onset form, on the delay of progression. There are also clinical reports of substrate reduction therapy using miglustat and bone marrow or hematopoietic stem cell transplantation. At the development stage there are methods of Tay-Sachs disease gene therapy using adeno- or adeno-associated viruses as vectors for the delivery of cDNA encoding α and β HexA subunit genes. Effectiveness of this approach is evaluated in α or β HexA subunit defective model mice or Jacob sheep, in which Tay-Sachs disease arises spontaneously and is characterized by the same pathological features as in humans. This review discusses the possibilities of new therapeutic strategies in Tay-Sachs disease therapy aimed at preventing neurodegeneration and neuroinflammation.
What are the causes of GM2 gangliosis?
GM2-gangliosidosis can be caused by mutations in three genes: HEXA (15th chromosome), HEXB (5th chromosome), and GM2A (5th chromosome) ( Mahuran, 1999; Ferreira and Gahl, 2017 ). GM2-gangliosidosis includes (I) Tay-Sachs disease (TSD, OMIM 272800), at which mutations occur in the HEXA gene and only HexA activity is disrupted (variant B); (II) Sandhoff disease (SD; OMIM 268800), caused by mutations in HEXB gene, at which the activity of HexA and HexB is disrupted (variant O); and (III) GM2 activator protein deficiency (OMIM 272750), at which mutations take place in the GM2A gene (variant AB) ( Mahuran, 1999 ).
What is GM2 gangliosidose?
GM2-gangliosidoses are a group of autosomal-recessive lysosomal storage disorders (LSDs). These diseases result from a deficiency of lysosomal enzyme β-hexosaminidase (Hex), which is responsible for GM2 ganglioside degradation ( Ferreira and Gahl, 2017 ). Gangliosides are the main glycolipids of neuronal cell plasma membranes which ensure normal cellular activities ( Sandhoff and Harzer, 2013 ). There are two major β-hexosaminidase isoenzymes: HexA consists of two subunits, α and β; HexB is a homodimer consisting of two β-subunits ( Ferreira and Gahl, 2017 ). The two subunits of HexA enzyme, α and β, are synthesized at the endoplasmic reticulum (ER) where glycosylation, the formation of intramolecular disulfide bonds and dimerization take place ( Weitz and Proia, 1992; Maier et al., 2003 ). Besides HexA and HexB isoenzymes a homodimer consisting of two α-subunits, called HexS, is also found ( Hou et al., 1996 ).
