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.
Huntingtonâs disease (HD) is a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain. It deteriorates a personâs physical and mental abilities during their prime working years and has no cure.very child of a parent with HD has a 50/50 chance of inheriting the expanded gene that causes the disease. If the child has not inherited this expanded gene, he or she will never develop the disease and cannot pass it on to their children. Huntington's disease is inherited in an autosomal dominant fashion.
