TS has been described in people of many ethnic origins. In the US, the CDC found that a diagnosis of TS was twice as likely for non-Hispanic white persons than for Hispanic and non-Hispanic black persons. However, this observation may be influenced by differences in seeking of healthcare rather than in actual symptomatic prevalence.
