Essay on Huntingtons Disease - An Overview - 1185 Words
Huntingtons Disease - An Overview Huntingtons Disease is a devastating and progressive neurological disorder that resu lts primarily from degeneration of nerve cells deep in the center of the brain. The condition was first described by George Huntington, a physician in New York, in 1872. Even then, the physician recognized the all-encompassing factors of the disorder when describing it as, coming on gradually but surely, increasing by degrees, and often occupying years in its development until the hapless sufferer is but a quivering wreck of his former self. The three most profound behavioral problems in Huntington s disease come from the uncontrollable movements called chorea, dementia, and the altered perception of theâ⬠¦show more contentâ⬠¦However, even as the disease progresses, people with the disorder almost always recognize their families, are aware of the situation, and have the ability to understand . Death usually occurs by aspiration pneumonia, malnutrition, or heart failure. At present, there is no cure for the disease, but dynamic progress has been made as researchers explore this illness. HD is inherited as an autosomal dominant condition. In March 1993, scientists realized that HD is caused by a mutation in a gene located on chromosome 4. This gene has a unique genetic sequence for CAG (cytosine-adenine-guanine) and codes for the amino acid glutamine, a building block for the huntingtin pr otein. Normal individuals have this sequence duplicated from 11 to 40 times in their genetic coding without having symptoms of HD. However, individuals with the disease have from 40 up to 100 repeated CAG segments. Juvenile Huntingtons Disease occurs wit h 60 or more repeats, linking the longer chains of CAG sequences to earlier and more aggressive onset of the disease. Current research revolves around the transgenic mouse model developed in Berlin at the Max Planck Institute. The model was made by p utting the first part of the HD gene, containing the long stutters of CAG repeats, into a mouse, and it was discovered that two months later the mice began to exhibit theShow MoreRelatedSymptoms And Treatment Of Huntington s Disease1263 Words à |à 6 Pages The name Huntingtonââ¬â¢s disease comes from an American physician, George Huntington (see figure 1), after he was the first person to give an official description of the disease in 1872 (Bhattacharyya, 2016). In Canada alone, more than 21 000 individuals have been affected by Huntingtonââ¬â¢s Disease, an incurable illness that results in death typically between 15-20 years after diagnosis (Scrivener, 2013). This disease causes both physical and mental changes in an individual, therefore completely changingRead MoreHuntingtonââ¬â¢s Disease Essay787 Words à |à 4 Pagesmuch about Huntingtonââ¬â¢s disease. After reading this paper and the subsequent ones to come, you surely will. According to PudMedHealth.com, ââ¬Å"Huntingtonââ¬â¢s disease is a disorder passed down through families in which nerve cells in certain parts of the brain waste away or degenerate.â⬠This can lead to many different complications to a personââ¬â¢s health. In most cases, the diseaseâ⠬â¢s symptoms develop later in life during a personââ¬â¢s mid thirties-forties. There are also instances where the disease becomes on-setRead MoreEssay Huntingtons Disease1113 Words à |à 5 PagesHuntingtons Disease Background Huntingtons disease is inherited as an autosomal dominant disease that gives rise to progressive, elective (localized) neural cell death associated with choleric movements (uncontrollable movements of the arms, legs, and face) and dementia. It is one of the more common inherited brain disorders. About 25,000 Americans have it and another 60,000 or so will carry the defective gene and will develop the disorder as they age. Physical deterioration occurs over a periodRead MoreThe Common Fruit Fly Drosophila Melanogaster913 Words à |à 4 PagesAssignment 3: Eyes in flies: An overview of the cinnabar gene and its relation to Huntington s diseaseâ⬠Introduction The common fruit fly Drosophila melanogaster is often regarded as the model organism for genetic testing due to many factors such as its short reproductive cycle, its similarities to humans, or the ease of tracking mutations in Drosophila melanogaster. The Drosophila melanogaster is used to model diseases such as Cancer, Diabetes, and Huntingtonââ¬â¢s Disease. By studying the changes in howRead MoreAre Antisense Oligonucleotides and Effective Trearment for Huntingtons Disease1486 Words à |à 6 Pagestreatments has already been seen in other disease, such as Vitravene (or Fomivirsen), which was the first ASO made publicly available, and is used to treat cytomegalovirus retinitis, as well as Isis 3521 which when given to lung cancer patients in addition to combination chemotherapy has been seen to raise life expectancy by as much as 50%[2].

This is done with DNA sequencing in adults and preimplantation genetic diagnosis (PDG) on embryos. These methods of genetic testing are effective means of determining the likelihood of developing diseases such as Huntingtonââ¬â¢s disease, a disease resulting from trinucleotide repeat on chromosome 4p16.3 that causes uncontrollable muscle movement and decrease in cognitive function.
