Do not worry, there is no evidence for the genetic transmission of Tourette's. Your children have no higher risk of having it than the general population. b.

There is a definite genetic component to Tourette's, but this is multigenic and so difficult to characterize the chances of your children having it. Only 10% of Tourette's patients do not have a relative with it, so you are likely to pass this disorder on. e. This disorder is inherited through an autosomal dominant mechanism. All of your sons and daughters will have Tourette's.
