Tourette Syndrome - Causes

Tourette syndrome is a genetic disorder. That is, the chance of having TS is greatly increased if some other family member also has the condition. If one parent has TS, his or her children have a higher than normal chance of developing the disorder. There is about a 50 percent chance that the child of a TS patient will inherit the TS gene. Male children with the TS gene are three to four times more likely to develop symptoms than are female children with the gene. However, only about 10 percent of those who inherit the TS gene develop symptoms that require medical attention.
