Huntington’s disease is a disease that causes parts of the brain to break down; degenerate. This disease doesn’t show it’s symptoms between the ages 30 and 50. The gene name is HTT, the official name is huntingtin.
HTT belongs to the family called endogenous ligands. It’s passed from one generation to the next, the size of CAG trinucleotide repeat often increase in size. A larger number of repeats is usually associated with an earlier onset of signs and symptoms. This phenomenon is called anticipation.
Huntington is found in many of the body’s tissues, with the highest levels of activity in the brain. This disease doesn’t show it’s symptoms between the ages 30 and 50, both men and women can have Huntington’s disease. …show more content…
It’s progress can’t be reversed neither slowed down. Treatments for this disease is to aim to improve any mood disturbance medication can help manage some of the symptoms, such as excessive …show more content…
This disease progresses slowly and the person may live for another 15-20 years later after the onset of symptoms.
People may ask, how is Huntington’s disease inherited? Well, everyone has two copies of the Huntington’s disease gene, but a person only has to have one changed copy of the gene to develop the disorder. The original copy cannot compensate for the effects of the copy with the changed. When people who have a Huntington’s disease gene with a mutation have children.
Huntington's testis done by measuring the number that repeats in Huntington's disease gene. In people who will develop Huntington's disease, this part of the gene is larger than usual. 39 or more repeats, the person will develop Huntington's disease at the same time. 35 or fewer repeats, the person will not develop the disease. Between 36 and 39 repeats, that person is not definitely in the unaffected range and is not defiantly in the affected range.
The people who has fewer than 35 repeats or more than 39 repeats, the test is virtually 100% accurate. For people with the intermediate number or repeats, between 35 and 39, the result is less certain, but this applies only to a small number of
