Thomas discovered a devastating piece of family historywhen he learned that his brother had been diagnosed withHuntington disease (HD) at age 49. This dominantly inheritedautosomal condition usually begins around age 45 with progressivedementia, muscular rigidity, and seizures and ultimatelyleads to death when affected individuals are in their early 60s. Therecurrently is no effective treatment or cure for this genetic disorder.Thomas, now 38, wonders what the chances are that he also hasinherited the mutant allele for HD, leading him to discuss with hiswife whether they should seek genetic counseling and whether heshould undergo genetic testing. They have two teenage children, aboy and a girl. Question : If you were in Thomas’s position, would you want to be testedand possibly learn that you were almost certain to develop thedisorder sometime in the next 5–10 years?

Question
Thomas discovered a devastating piece of family history
when he learned that his brother had been diagnosed with
Huntington disease (HD) at age 49. This dominantly inherited
autosomal condition usually begins around age 45 with progressive
dementia, muscular rigidity, and seizures and ultimately
leads to death when affected individuals are in their early 60s. There
currently is no effective treatment or cure for this genetic disorder.
Thomas, now 38, wonders what the chances are that he also has
inherited the mutant allele for HD, leading him to discuss with his
wife whether they should seek genetic counseling and whether he
should undergo genetic testing. They have two teenage children, a
boy and a girl.
Question : If you were in Thomas’s position, would you want to be tested
and possibly learn that you were almost certain to develop the
disorder sometime in the next 5–10 years?
