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 hexosaminidase A, often called hex A, an enzyme whose activity helps distinguish carriers and affected individuals from those who are not carriers.
About Tay-Sachs Disease Testing | Carrier Test in Washington
Tay-Sachs disease testing examines the activity of hexosaminidase A, an enzyme involved in breaking down certain fatty substances in nerve cells.
Tay-Sachs disease is caused by changes in the HEXA gene, which provides instructions for producing the enzyme hexosaminidase A. When this enzyme is absent or severely reduced, fatty substances called GM2 gangliosides accumulate in the brain and nervous system, leading to progressive neurological damage.
Carrier testing measures hex A enzyme activity in a blood sample. Carriers typically have lower-than-normal enzyme activity but do not develop the disease. Individuals with Tay-Sachs disease have very low or undetectable enzyme activity. Because enzyme levels can overlap in some cases, follow-up genetic testing may be recommended to confirm a carrier result.
Tay-Sachs disease follows an autosomal recessive inheritance pattern. A child is affected only when both parents are carriers and both pass on a changed copy of the HEXA gene. Carrier testing is therefore most informative when it is considered alongside family history and, when appropriate, the partner's carrier status.
