DIRECT GENETIC TESTING. Huntingtonâs disease has become a model for genetic testing in other adult-onset inherited disorders because the illness is relatively common, and there is widespread experience with it. Genetic testing programs began in 1986 with linkage testing and evolved to direct gene testing shortly after the gene was cloned in 1993.
Every person inherits two copies of the Huntington gene, one from each parent. Likewise, every person will also pass one of these two copies to each child. The chances of giving either of these two alleles to a child are equal (50/50). A person with Huntingtonâs disease has one non-HD allele and one HD allele.very person inherits two copies of the Huntington gene, one from each parent.
