Order Tay-Sachs Disease Testing | Carrier TestTay-Sachs disease is an inherited condition that affects the nervous system, and carrier testing can clarify whether a person carries a gene change associated with it. This blood test measures hexosaminidase A, often called hex A, an enzyme whose activity helps indicate carrier status or the presence of the disease.
About Tay-Sachs Disease Testing | Carrier Test in Laredo
Understanding Tay-Sachs disease and hex A testing
Tay-Sachs disease results from changes in the HEXA gene, which provides instructions for producing the enzyme hexosaminidase A. This enzyme normally helps break down a fatty substance called GM2 ganglioside. When hex A activity is very low or absent, that substance accumulates in nerve cells, particularly in the brain and spinal cord, leading to progressive neurological damage.
Carrier testing measures hex A activity in a blood sample to assess whether a person carries one altered copy of the HEXA gene. Carriers typically have reduced but not absent enzyme activity, and they generally do not develop symptoms. Because the condition is inherited in an autosomal recessive pattern, two carriers have a chance of having an affected child with each pregnancy.
Hex A testing is most informative when paired with genetic counseling and, when appropriate, DNA analysis. Enzyme activity can vary with age, pregnancy, and certain other health conditions, so results are interpreted alongside a person's history and, in some cases, additional molecular testing. This test is not a diagnosis on its own; it is one piece of a broader evaluation.
