The Tay-Sachs disease (TSD) is a rare autosomal, recessive genetic disorder which is caused by accumulation of lipids in the brain. This leads to the cell death of those neurons. There exist three different variations of the TSD. The most common one is the Infantile Tay-Sachs disease which affects death of the children under the age of 5. The two other variants are the Juvenile and Adult/Late Onset TSD, which are less aggressive. The disease causes a deterioration of mental and physical abilities. Sadly, there currently exists no treatment.
