Order Tay-Sachs Disease Testing | Carrier TestTay-Sachs disease is a rare genetic disorder that progressively destroys nerve cells in the brain and spinal cord. This test measures the level of hexosaminidase A (hex A) in the blood to determine whether an individual has Tay-Sachs disease or is a carrier.
About Tay-Sachs Disease Testing | Carrier Test in Ashburn
Tay-Sachs disease is an inherited condition caused by mutations in the HEXA gene, which provides instructions for producing the enzyme hexosaminidase A.
Hex A is essential for breaking down a fatty substance called GM2 ganglioside in nerve cells. When Hex A is deficient, GM2 ganglioside accumulates to toxic levels, leading to the destruction of neurons.
The most common form, infantile Tay-Sachs, typically appears in infancy and leads to progressive loss of motor skills, seizures, and other neurological symptoms. Carrier individuals have one mutated copy of the HEXA gene and one normal copy, usually without symptoms, but they can pass the mutation to their children.
This blood test measures Hex A enzyme activity. Low or absent activity indicates Tay-Sachs disease, while reduced activity may indicate carrier status. Genetic testing can provide additional information.
