Order Tay-Sachs Disease Testing | Carrier TestTay-Sachs disease is an inherited condition that affects the nervous system, and testing can reveal whether a person carries the genetic change associated with it. This blood test measures the activity of hexosaminidase A, often called hex A, an enzyme whose deficiency is central to the disorder.
About Tay-Sachs Disease Testing | Carrier Test in Grapevine
Tay-Sachs disease testing centers on an enzyme that the body relies on for normal nerve cell function.
Tay-Sachs disease results from changes in the HEXA gene, which provides instructions for making the enzyme beta-hexosaminidase A. This enzyme helps break down a fatty substance called GM2 ganglioside inside cells. When the enzyme is missing or reduced, the substance accumulates, particularly in nerve cells, and leads to progressive neurological damage.
The classic form of Tay-Sachs disease typically appears in infancy, with symptoms such as loss of motor skills, exaggerated startle response, and vision changes. Carrier status, by contrast, usually produces no symptoms. Carriers have one altered copy of the HEXA gene and one typical copy, and they can pass the altered copy to a child.
Enzyme testing measures hex A activity in a blood sample. Low or absent activity can indicate Tay-Sachs disease, while reduced activity compared with normal may suggest carrier status. Because enzyme levels can overlap between groups, results are often interpreted alongside genetic testing and family history. A healthcare provider determines what further evaluation, if any, is appropriate.
