Dominant Patterns of Genetic Inheritance – Huntington’s Disease. “People . at-risk for the disease face a difficult choice about genetic testing for HD, given the current absence of an effective treatment or cure. Many people see no benefit in knowing that they will someday develop the disease. Others want an end to uncertainty so that they can make informed choices about the future.
