Who does it effect?
|
It occurs relatively frequently in Ashkenazi Jews and rarely in blacks. About three-quarters of patients are male, and 10% of affected individuals have a family history of the disorder. Those most at risk are sons of mothers with TS, where the percentage who develop it may be as high as 30%. The specific mode of genetic transmission has not been established. Some hold susceptibility to TS is conveyed by a single major gene in combination with a multifactorial background. Familial cases suggest that TS is an autosomal dominant trait with sex thresholds that affect the expression of the disorder. However, many sporadic cases have been reported. The incidence of full-blown cases of TS is estimated to be one in 2,000 live births. Mild cases may appear as frequently as one in 200 or one in 300 live births. It is said to be unusually frequent in a Mennonite religious isolate population in Canada.
