Genetic testing for Huntington's disease has raised several ethical issues. The issues for genetic testing include defining how mature an individual should be before being considered eligible for testing, ensuring the confidentiality of results, and whether companies should be allowed to use test results for decisions on employment, life ...
However, in individuals affected by Huntington's disease (an autosomal dominant genetic disorder), the polymorphic locus contains more than 36 glutamine residues (highest reported repeat length is about 250). [7] Its commonly used name is derived from this disease; previously, the IT15 label was commonly used.
Huntington's disease is a neurodegenerative disease and most common inherited cause of chorea. The condition was formerly called Huntington's chorea but was renamed because of the important non-choreic features including cognitive decline and behavioural change.
Due to the wide range of genetic disorders that are known, diagnosis is widely varied and dependent of the disorder. Most genetic disorders are diagnosed pre-birth, at birth, or during early childhood however some, such as Huntington's disease, can escape detection until the patient begins exhibiting symptoms well into adulthood.

These often are translated into polyglutamine-containing proteins that form inclusions and are toxic to neuronal cells. Examples of the disorders caused by this mechanism include Huntington's disease and Huntington disease-like 2, spinal-bulbar muscular atrophy, dentatorubral-pallidoluysian atrophy, and spinocerebellar ataxia 1–3, 6–8, and 17.
Nancy Wexler; current president of the HDF. In 1968, after experiencing Huntington's disease (HD) in his wife's family, Milton Wexler was inspired to start the Hereditary Disease Foundation, with the aim of curing genetic illnesses by co-ordinating and supporting research. [1]
Huntington's disease is an autosomal dominant mutation in the HTT gene. The disorder causes degradation in the brain, resulting in uncontrollable movements and behavior. [17] The mutation involves an expansion of repeats in the Huntington protein, causing it to increase in size. Patients who have more than 40 repeats will most likely be affected.
