Of course: Short parents have tall kids, parents without epilepsy have kids with it, straight parents have gay kids, & so on & on forever. If the number of CAG repeats in the huntingtin gene increases from normal to abnormal from parent to child, then the child will have Huntington's. Look at hdsa.org and elsewhere for more information.
