Of course, high rates of potential interest may not translate into widespread genetic testing. The best illustration of this difference comes from people at risk for Huntington’s disease, of whom 40–79% express some intention to get tested, but only 9–20% actually utilize the test. (Meiser & Dunn, 2000) However, the previously noted differences between degenerative conditions such as Huntington’s disease and most psychiatric disorders may limit the ability to extrapolate from these data to the disorders being considered here.
