Order Tay-Sachs Disease Testing | Carrier TestTay-Sachs disease is a rare inherited condition that affects the nervous system, and carrier testing can reveal whether a person carries a genetic change associated with it. This blood test measures the activity of hexosaminidase A (hex A), an enzyme whose deficiency underlies the disorder.
About Tay-Sachs Disease Testing | Carrier Test in Belleville
Tay-Sachs disease testing examines enzyme activity to identify affected individuals and carriers.
Tay-Sachs disease results from variants in the HEXA gene that reduce or eliminate the activity of hexosaminidase A, an enzyme involved in breaking down a fatty substance called GM2 ganglioside. When this enzyme is deficient, GM2 ganglioside accumulates in nerve cells, leading to progressive neurological damage.
Carrier testing measures hex A activity in the blood. Carriers typically have lower-than-normal enzyme levels but do not develop the disease. Affected individuals have markedly reduced or absent enzyme activity. Because enzyme levels can overlap between groups, results are sometimes confirmed with DNA analysis of the HEXA gene.
Tay-Sachs disease is inherited in an autosomal recessive pattern, meaning a child must inherit a genetic change from both parents to be affected. Carriers are generally healthy and often unaware of their status. Testing is most informative for individuals with a family history or those in populations where the condition is more common.
