The vulnerability to Tourette's Disorder and related disorders is transmitted in an autosomal dominant pattern. "Vulnerability" implies that the child receives the genetic or constitutional basis for developing a Tic Disorder; the precise type or severity of disorder may be different from one generation to another. Not everyone who inherits the genetic vulnerability will express symptoms of a Tic Disorder. Penetrance in female gene carriers is about 70%; penetrance in male gene carriers is about 99%. The range of forms in which the vulnerability may be expressed includes full-blown Tourette's Disorder, Chronic Motor or Vocal Tic Disorder, some forms of Obsessive-Compulsive Disorder, and, perhaps, Attention-Deficit/Hyperactivity Disorder. In about 10% of those with Tourette's Disorder, there is no evidence of a familial pattern. Individuals with these "nongenetic" forms of Tourette's Disorder or another tic disorder often have another mental disorder (e.g., Pervasive Developmental Disorder) or a general medical condition (e.g., a seizure disorder).
