Hex A is an enzyme that is necessary for normal nerve cell function. A deficiency of Hex A is caused by an inherited genetic mutation known as Tay-Sachs disease (TSD), which is a progressive loss of motor control which usually leads to death by the age of eight. When a person has only one gene, they are a carrier of TSD and will not develop the disease themselves, but they can pass the genetic mutation along to their children. Since TSD is caused by a recessive gene, the gene must be inherited from both parents in order to develop the disease. There are many methods used to perform this test; check with the lab that is performing your test for the normal levels.
