Tay-Sachs disease is an inherited condition that’s quite rare but can be concerning for some couples. If you’re curious about what it is, how it happens, and what you can do about it, you’ve come to the right place.
What is Tay-Sachs Disease?
Tay-Sachs is a genetic disorder that leads to the gradual breakdown of nerve cells in a baby’s brain and spinal cord. For an infant to be affected, both parents need to be carriers of the Tay-Sachs gene and pass it on to their child. Babies usually seem perfectly healthy at birth, but signs of the disease typically emerge between 3 and 6 months of age.
What Causes Tay-Sachs Disease?
The condition arises when a child inherits two copies of the Tay-Sachs gene—one from each parent. If this happens, the baby lacks the essential enzyme beta-hexosaminidase A (HEX-A), which is crucial for breaking down fatty waste in the body. Without this enzyme, harmful substances build up in the brain and spinal cord, leading to serious health issues.
Who is at Risk?
Couples of Ashkenazi Jewish descent are at a higher risk of being carriers, but Tay-Sachs can affect anyone. If you’re thinking about starting a family and want to know if you might be at risk, consider getting screened for the Tay-Sachs gene.

Screenings for Tay-Sachs Disease
Screening is a straightforward blood test that can determine if you or your partner are carriers. If both of you test positive, there are options to consider, including pre-implantation genetic diagnosis (PGD) during in vitro fertilization (IVF).

Probability of Having a Child with Tay-Sachs Disease
If both parents are carriers, there is a 25% chance that their child will be affected by Tay-Sachs. Knowing your carrier status can help you make informed choices about family planning.
Symptoms of Tay-Sachs Disease in Babies
Symptoms can include a lack of responsiveness, decreased motor skills, and an exaggerated startle response. Unfortunately, Tay-Sachs is a progressive condition without a cure. However, various treatments can help manage symptoms and improve quality of life.
Treatment Options
While there’s no cure, supportive treatments are available. These might include physical therapy, special education, and nutritional support. The goal is to provide the best quality of life for the baby as long as possible.
