Extractions: Presentation is usually at six months of age when affected infants, who previously have appeared normal and passed their early milestones, become lethargic, floppy and poor feeders. They show an abnormal accentuated startle response to sudden noises. There is usually a macular cherry-red spot. Motor development becomes progressively retarded and as the disease progresses blindness, spasticity and decerebrate rigidity occur. Feeding becomes increasingly difficult and death usually occurs by 3 years following pulmonary infection. Later onset forms of the disease with juvenile or adult presentation and sub-acute or chronic courses also occur. In these there may be survival into adolescence, or longer survival with normal intelligence but slowly progressive spinocerebellar degeneration. Enzyme Test: b -Hexosaminidase A is measured for diagnosis of this disease.

Extractions: Tay-Sachs disease results in the deterioration of the nervous system, usually resulting in death before the patient reaches age 5. It is caused by the absence of an enzyme which breaks down lipids, resulting in a lethal accumulation in cells. There is no treatment, but potential parents can be identified as carriers for the disease with a blood test.

Health Topics A-Z Search 1Up Health Tay-Sachs disease Information Tay-Sachs disease Causes, Incidence, and Risk Factors Definition : A familial disorder found predominantly in Ashkenazi Jewish families, which results in early death. Tay-Sachs disease is caused by a deficiency of hexosaminidase, an enzyme that is important in the metabolism of gangliosides (a type of chemical substance found in nerve tissue). These gangliosides, particularly ganglioside GM2, then accumulate in the brain, causing neurological deterioration. Tay-Sachs disease is inherited as a recessive gene, and 1 out of every 25 members of the Ashkenazi Jewish population carries the gene. The incidence is 1 out of 2,500 people in this population. Depending on the age of onset and clinical features, Tay-Sachs has been classified into infantile-, juvenile-, and adult-onset forms. The majority of people with Tay-Sachs, however, have infantile forms. Symptoms begin to appear at 3 to 6 months old. The disease unfortunately tends to progress rapidly, and the child usually dies by the age of 4 or 5 years.

http://www.nfjgd.org/diseases/tay-sachs.shtml

Extractions: Diseases: Tay-Sachs Disease ay-Sachs disease is the most well known Jewish genetic disease, potentially affecting one in every 2,500 Ashkenazi Jewish newborns. Two forms of this disease occur in Ashkenazi Jews, the well known infantile-onset form and a lesser known, late-onset or adult form designated "chronic GM2-gangliosidosis". Infantile Tay-Sachs Disease This disease is characterized by the onset of severe mental and developmental retardation during the first four to eight months of life. An early sign of the disease is the cherry-red spot, an unusual abnormality in the retina of the eye observed only by use of an ophthalmoscope. The involvement of the central nervous system progresses rapidly and affected children become totally debilitated by two to five years of life. Affected children also develop seizures which are not controllable with anti-epileptic drugs. Death usually occurs by three to five years of life due to pneumonia or other infections. Tay-Sachs disease is an inherited metabolic disorder. The basic defect in affected children is the deficiency of an enzyme , Beta-hexosaminidase A. This enzyme normally breaks down a naturally occurring fatty substance called GM2-ganglioside. The enzyme deficiency leads to a toxic accumulation of GM2-ganglioside in the cells of the nervous system. The gene for hexosaminidase A has been isolated on

Tay-Sachs Disease
taysachs disease. Definition tay-sachs disease is a genetic disorder. A missingenzyme results in the accumulation of a fatty substance in the nervous system.
http://www.chclibrary.org/micromed/00067340.html

Extractions: Gangliosides are a fatty substance necessary for the proper development of the brain and nerve cells (nervous system). Under normal conditions, gangliosides are continuously broken down, so that an appropriate balance is maintained. In Tay-Sachs disease, the enzyme necessary for removing excess gangliosides is missing. This allows gangliosides to accumulate throughout the brain, and is responsible for the disability associated with the disease. Tay-Sachs disease is particularly common among Jewish people of eastern European and Russian (Ashkenazi) origin. About one out of every 3,600 babies born to Ashkenazi Jewish couples will have the disease. Tay-Sachs is also more common among certain French-Canadian and Cajun French families. Tay-Sachs is a genetic disease, caused by a defective gene. Genes are located on chromosomes, and serve to direct specific development/processes within the body. Because it is a recessive disorder, only people who receive two defective genes (one from the mother and one from the father) will actually have the disease. People who have only one defective gene and one normal gene are called carriers. They carry the defective gene and thus the possibility of passing the gene and/or the disease on to their offspring.

Extractions: Tay-Sachs disease is a fatal genetic disorder that occurs more frequently in the Ashkenazi (Eastern European) Jewish population. Approximately 1 in 27 Ashkenazi Jewish individuals are carriers of this disease. A baby with Tay-Sachs disease appears normal at birth, but after six months of age, the child progressively develops mental retardation followed by paralysis, blindness, and seizures. Death usually occurs by the age of five. Tay-Sachs disease is caused by a deficiency of an enzyme called Hex-A. As a result of this deficiency, there is an accumulation of certain substances which damage the nervous system. Tay-Sachs is an autosomal recessive disorder, which means for an individual to be affected with the disease, he/she must inherit one copy of the abnormal (mutated) Tay-Sachs gene from each parent. Individuals with one copy of the abnormal gene and one copy of the normal gene are known as carriers. Carriers usually do not have any symptoms of the disorder. How Can Tay-Sachs Be Detected?
