Tay-Sachs Genetic Testing

Tay-Sachs disease is an inherited disease that results in a deficiency of Hex A, an enzyme necessary for normal nerve cell function. This enzyme deficiency causes is a progressive loss of motor control in children, which usually results in death by the age of eight. Tay-Sachs Genetic mutation is a recessive gene; the gene must be inherited from both parents in order to develop the disease. People who have only received one gene are carriers and will not develop the disease, but the gene can be passed along to their children.
