Is TS a genetic disorder?
In most cases, TS is an inherited disorder. The chance that a parent with TS will pass tic symptoms to their child is estimated at about 40% to 50%. Sons of a parent with TS are about 4 times more likely to have tics in comparison to daughters. In many cases, however, the children of affected parents will have a mild form of the syndrome. Statistics indicate that only about 10% of the children who inherit the gene will have symptoms severe enough to require medical treatment.
