May 15, iStock If you and your partner are of Jewish or French Canadian descent, you may want to speak with your doctor about getting tested for this rare, but inherited, disease. When you're pregnant, your routine prenatal tests will screen your baby-to-be for the most common chromosomal disorders and conditions.

So, as those fatty proteins build up in the brain, they hurt the baby's sight, hearing, movement, and mental development. Tay-Sachs can be detected before birth, so couples who are thinking of having children may want to get a blood test to find out whether their child would be likely to have it.

Who Is at Risk for Tay-Sachs? Each year, about 16 cases of Tay-Sachs are diagnosed in the United States. Some people carry the genetic mutation that causes Tay-Sachs, but do Tay sachs baby develop the full-blown disease.

A child can only have Tay-Sachs disease if both parents are carriers of the gene. When two carriers have a child together, there's a: If the tests do detect HEXA, the infant will not have it. Between the 10th and 12th weeks of pregnancy, an expectant mother can get a chorionic villus sampling CVSin which a small sample of the placenta is drawn into a needle or a small tube for analysis.

In this test, a needle is inserted into the mother's belly to draw a sample of the amniotic fluid that surrounds the fetus. Signs and Symptoms Kids are usually tested for Tay-Sachs after having hearing, sight, and movement problems.

A doctor can identify the disease with a physical exam and blood tests. A baby born with Tay-Sachs develops normally in the first 3 to 6 months of life. During the next months — or even years — the baby will progressively lose the ability to see, hear, and move.

A red spot will develop in the back of the child's eyes. The child will stop smiling, crawling, turning over, and reaching out for things.

By age 2, the child may have seizures and become completely disabled. Death usually occurs by the time the child is 5 years old. In rare forms of the disease, a child may have the HEXA enzyme, but not enough of it to prevent developmental problems. In one of these forms, called juvenile HEXA deficiency, those problems may not appear until the child is 2 to 5 years old.

The disease progresses more slowly, but death usually occurs by the time the child is 15 years old. In another, milder form of Tay-Sachs called late-onset Tay-Sachsthe disease causes muscle weakness and slurred speech, but sight, hearing, and mental capabilities remain intact.

But doctors may be able to help a child cope with its symptoms by prescribing medicines to relieve pain, manage seizures, and control muscle spasticity. Researchers are studying ways to improve treatment of and screening for Tay-Sachs disease. If your child has been diagnosed with Tay-Sachs or both you and your partner are carriers of the gene, talk to your doctor or a genetic counselor about ongoing research.Tay-Sachs and Sandhoff diseases are rare, inherited diseases that affect a baby’s central nervous system (the brain and spinal cord).

The central nervous system controls how the body works.

Sandhoff disease is a severe form of Tay-Sachs. Tay-Sachs disease occurs when the body lacks hexosaminidase A. This is a protein that helps break down a group of chemicals found in nerve tissue called gangliosides. Without this protein, gangliosides, particularly ganglioside GM2, build up in cells, often nerve cells in the brain.

Tay-Sachs. A baby with Tay-Sachs disease is born without an important enzyme, so fatty proteins build up in the brain, hurting the baby's sight, hearing, movement, and mental development.

Tay-Sachs and Sandhoff diseases are rare, inherited diseases that affect a baby’s central nervous system (the brain and spinal cord). The central nervous system controls how the body works. Sandhoff disease is a severe form of Tay-Sachs. Tay-Sachs and Sandhoff diseases are rare, inherited diseases that affect a baby’s central nervous system (the brain and spinal cord). The central nervous system controls how the body works. Sandhoff disease is a severe form of Tay-Sachs. Tay-Sachs disease is a rare, inherited disorder that’s passed down from parents to child, and causes a progressive deterioration of the nerve cells in a baby's brain and spinal cord. In order for an infant to have this disease, both parents must be carriers of Tay-Sachs and .

What is Tay-Sachs disease? Tay-Sachs disease (the most severe form of Hexosaminidase A deficiency) is a progressive, fatal genetic condition that affects the nerve cells in the brain.

People with Tay-Sachs lack a specific protein (enzyme) called hexosaminidase A. Tay-Sachs disease (TSD) is a fatal genetic disorder, most commonly occurring in children, that results in progressive destruction of the nervous system.

Tay-Sachs is caused by the absence of a vital enzyme called hexosaminidase-A (Hex-A). Tay-Sachs disease is a rare, inherited disorder that’s passed down from parents to child, and causes a progressive deterioration of the nerve cells in a baby's brain and spinal cord.

In order for an infant to have this disease, both parents must be carriers of Tay-Sachs and .
