Tay-Sachs disease (TSD) is a rare genetic disease that stops the nerves from working the right way. It mostly affects babies and young children. This condition causes early death in children. Adults who get it may live to 60 years of age.
TSD is caused by a faulty gene that is passed down from both parents. The faulty gene results in a missing enzyme. This enzyme is needed to break down a fatty substance. When this substance builds up in the brain it causes damage.
