Tay-Sachs disease is a rare, hereditary disease which affects young children, primarily Ashkenazi Jews, French Canadians and other isolated or self-selecting populations. It is caused by the lack of an enzyme that leads to a buildup of fats in nerve and brain cells, resulting in loss of mental and physical abilities.
