The gene is also called HD and IT15which stands for ‘interesting transcript 15’. Archived from the original on 4 March Association of British Insurers. Dentatorubral-pallidoluysian atrophy Huntington’s disease Kennedy disease Spinocerebellar ataxia 1, 2, 3, 6, 7, 17 Machado-Joseph disease. Mutant Huntingtin is expressed throughout the body and associated with abnormalities in peripheral tissues that are directly caused by such expression outside the brain.

One way of accomplishing this is to identify polymorphisms present on only one allele and produce gene silencing drugs that target polymorphisms in only the mutant allele.

American Journal of Medical Genetics. A Study in Heredity”. Archived from the original on 19 November Nervous and Mental Disease. These implications include the impact on an individual’s psychology, career, family planning decisions, relatives and relationships.


Huntington’s disease – Wikipedia

There is no cure for HD, but there are treatments available to reduce the severity of some of its symptoms. Retrieved 1 April Brain herniation Reye’s Hepatic encephalopathy Toxic encephalopathy Hashimoto’s chorwe.

Their functions are not fully understood, but current theories propose that they are part of the cognitive executive system [17] and the motor circuit. The Journal of Neuropsychiatry and Clinical Neurosciences.

An amniocentesis can be performed if the pregnancy is further along, within 14—18 weeks. Neurology, Psychiatry and Brain Research 8: Archived from the original on 22 October Delirium Post-concussion syndrome Organic brain syndrome. This would require parts of the process to be kept secret from the parent. Histone modifications in Huntington’s disease”. During the rediscovery of Mendelian inheritance at the turn of the 20th century, HD was used tentatively as an example of autosomal dominant inheritance.

Also covered is information concerning family planning huntihgton, care management, and other considerations. Access to the text HTML.

Mutant Huntingtin protein has been found to play a key role in mitochondrial dysfunction. Archived from the original on 20 September Huntington’s Disease Society of America. HD Society of Canada. Research into the mechanism of HD has focused on identifying the functioning of HTT, how mHTT differs or interferes with it, and the brain pathology that the disease produces.


Even before the onset of symptoms, genetic testing can confirm if an individual or embryo carries an expanded copy of the trinucleotide repeat in the HTT gene that causes the disease. Common consequences are physical instability, abnormal facial expression, and difficulties chewing, swallowingand speaking.

Trends in Biochemical Sciences. Neuroticstress -related and somatoform.

Archived from the original on 12 May The rate of occurrence is highest in peoples of Western European descent, averaging around 7 perpeople, and is huntingtton in the rest of the world; e.

If these are abrupt and have random timing and distribution, they suggest a diagnosis of HD.

Huntington’s disease

Huntington described the exact pattern of inheritance of autosomal dominant disease years before the rediscovery by scientists of Mendelian inheritance. It interacts with proteins which are involved in transcription, cell signalingand intracellular transporting.

Early symptoms are attributable to functions of the striatum and its cortical connections—namely control over movement, mood and higher cognitive function. The accumulating damage to this area causes the characteristic erratic movements associated with HD.
