Tay-Sachs and Who It Affects Tay-Sachs disease is rare in the general population. The genetic mutations that cause this disease are more common in people of Ashkenazi (eastern and central European) Jewish heritage than in those of other backgrounds. Approximately 1 in every 27 Jews in the United States is a carrier of the Tay-Sachs disease gene.

Tay-Sachs Disease - Topic Overview Tay-Sachs is a rare disease that is passed down through some families. A person with Tay-Sachs has changed (mutated) genes that don't make any or enough of an enzyme called hexosaminidase A (hex A). Hex A breaks down fatty compounds. Without it, fatty compounds build up in the brain and nerve cells and cause damage.

- 1 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. 2  In contrast to the other forms, late-onset Tay–Sachs disease is usually not fatal as the effects can stop progressing.

Tay-Sachs Disease A defective gene on chromosome 15 causes Tay-Sachs disease. This defective gene causes the body to not make a protein called hexosaminidase A. Without this protein, chemicals called gangliosides build up in nerve cells in the brain, destroying brain cells.ay-Sachs is a disease of the central nervous system; it is a neurodegenerative disorder. Tay-Sachs most commonly affects infants. In infants, it is a progressive disease that is unfortunately always fatal. Rarely, Tay-Sachs can occur in teens and adults, causing less severe symptoms.

- The month of May is designated as Tay-Sachs and Canavan Diseases Awareness Month. Newborns with Tay-Sachs disease appear healthy at birth, but then symptoms start to occur at 6 months. The infant will start to lose motor skills and mental functions.

- If you or your doctor thinks that your child has Tay-Sachs disease, your doctor will do a physical exam and a blood test to check the level of hex A. A genetic test may be needed to be sure the disease is Tay-Sachs.

Tay-Sachs Disease Those with the chronic form of Tay-Sachs develop symptoms by the age of 10, but the disease progresses slowly. Symptoms may include slurred speech, muscle cramps, and tremors. Life expectancy varies with this form of the disease, and some individuals have a normal lifespan.

Causes of Tay-Sachs The cause of Tay-Sachs disease is a genetic defect (mutation) that is passed from parent to child. This genetic defect is located in the HEXA gene, which is found on chromosome 15. The HEXA gene makes part of an enzyme called beta-hexosaminidase A, which plays a critical role in the nervous system.

Tay-sachs Disease Children with Tay-Sachs disease lack a vital enzyme, hexosaminidase A (Hex-A). Hex-A is needed for the body to break down a fatty waste substance found in brain cells. Without Hex-A, this substance accumulates abnormally and causes progressive damage until the nervous system can no longer sustain life.

Tay-Sachs Disease Back to Top Causes. Tay-Sachs disease occurs when the body lacks hexosaminidase A, a protein that helps break down a chemical found in nerve tissue called gangliosides.

Chapter 5 Genetic Disorders Tay-Sachs disease is caused by a mutation in the HEXA gene. A genetic mutation is a permanent alteration in the DNA sequence that makes up a gene. It causes one or more processes of the body to not work properly. A mutated HEXA gene results in the body not producing an enzyme called Hexosaminidase-A (Hex-A).Without this enzyme, a fatty substance called GM2 ganglioside builds up in the cells of the brain and nerves, and stops them working normally, eventually destroying them.ay-Sachs disease is a rare and usually fatal genetic disorder that causes progressive damage to the nervous system.

How does tuberculosis affect the body? A , Family Medicine, answered. Tuberculosis (TB) can affect different parts of the body. TB is caused by a bacterium that typically affects the lungs, but can also affect other areas such as the brain, kidney, or spine. Some people who have been exposed to TB have latent TB, which does not cause them to have symptoms.

- The focus of treatment for Tay-Sachs disease is to control symptoms and make your child as comfortable as possible. There is no cure. It may be helpful to seek counseling or find support from others who are going through the same thing you are.

TayâSachs disease Tay–Sachs disease is caused by a genetic mutation in the HEXA genes on chromosome 15. It is inherited from a person's parents in an autosomal recessive manner. The mutation results in problems with an enzyme called beta-hexosaminidase A which results in the buildup of the molecule GM2 ganglioside within cells, leading to toxicity.
