Analyzing Huntington's Disease

Improved Essays
Huntington’s disease is a progressive and fatal type of dementia caused by dominant allele in chromosome 4. (Kail & Cavanaugh, 2016, 2013, 2010, p. 44) It is an autosomal-assertive, progressive neurodegenerative affliction with a definite phenotype, including chorea, lack of coordination, cognitive deterioration, and behavioral difficulties. (Perandones, Micheli, & Radrizzani, 2010, p. vii)
Huntington’s disease was identified by George Huntington in 1872. Huntington Disease is also referred to as Huntington chorea or heredity chorea. (Gulli & Frey, 2011, p. 16) Chorea is spontaneous, forceful, rapid convulsive movements that may be slight or develop into confluent, notably changing normal patterns of movement. ("Chorea," 2015) George Huntington said in his paper “On Chorea,” “There are marked peculiarities in this disease: 1. Its hereditary nature. 2. A tendency to insanity and suicide. 3. Its manifesting itself as a grave disease only in adult life” (Bates, Tabrizi, & Jones, 2014, p. 4)

("Testing for HD," p. 3) If one or both parents display symptoms of Huntington’s, especially if the symptoms are serious, one or more of the offspring will almost always suffer from this disease. If the offspring somehow goes through life without developing the disease the cycle is broken. This means that any offspring born from

    Huntington Disease Introduction Case 2 presents a story of two brothers Brain and Jeff, whose father was diagnosed some time ago with Huntington’s disease (HD). Upon realization that the father may not live too long, Brain decided to reconcile with his father. Jeff however cannot forgive him the fact that he left the family and refuses to visit his father. The communication between two brothers ceases to the point that Jeff does not want to know anything about his father and his illness. After Brain learns that he tested positive for the HD, he initially wants to tell his brother about this fact, but ultimately, influenced by negative emotion of anger to Jeff, he changes his mind and decides not share this news with him.…

    Review Questions # 5 2. Distinguish between autosomal dominant and autosomal recessive disorders and provide a couple examples of each. When dealing with genetic disorders its important to understand how they are inherited. There are two ways a child can inherited a genetic disorder from their parents. Autosomal dominant disorder is where one parent has a genetic disorder in which it has already manifested such as familial hypercholesterolaemia, marfan’s syndrome, and achondroplasia(dwarfism) and this dominant gene is inherited by their child who will also develop the disorder.…

    Test: MIRBI-2: Mini Inventory of Right Brain Injury- Second Edition Authors: Patricia A. Pimental and Jeffrey A. Knight Test Implications: The MIRBI-2 has 5 implications that test administrators should consider prior to giving the test. The 5 principal uses include identifying adults who have difficulties that are consistent with those who have right hemisphere brain injuries; comparing the current levels of functioning to prior levels of functioning; utilizing Pimental’s RHD classification system; using the individual’s performance on the MIRBI-2 to begin the process of therapy and related goals; contributing to scientific research concerning individuals with RHD. Normative Age: 20-80 years Normative Language: English Normative Population: The MIRBI-2 was normed on 128 patients who had RHD, 45 patients who had LHD, and 78 individuals as a control group. Male participants contributed to 49% of the normative population, while female participants contributed to 51% of the normative population.…

    1. Is it true that a homozygous dominant father and a homozygous recessive mother could give birth to a homozygous recessive child with the disorder phenotype? Explain. From the information provided, it can be determined that this statement is not true, as the offspring of this couple will not be homozygous recessive for the given trait. As both of the parents are homozygous for their respective alleles, every child would receive an allele from each parent, one being dominant (D) and the other being recessive (d).…

    Huntington’s Disease (HD or HTT), also known as Huntington’s Chorea, is a deadly autosomal dominant inherited neurodengerative disease that causes progressive deterioration of the nerve cells in the brain. HD is distinguished by continuous motor, behavioral and cognitive decline, eventually ending in death. Huntington’s Disease weakens the individuals physical and psychological abilities throughout their prime. Every offspring has a 50/50 chance of carrying the defective gene. There are roughly 30,000 Americans with the symptoms, and more than 200,000 at risk of getting the disease.…

    OVERVIEW: Huntington's disease (HD) is an inherited disorder that causes degeneration of brain cells, called neurons, in motor control regions of the brain, as well as other areas (NINDS, 2016). Huntington’s disease is caused by a mutation in the gene for a protein called huntingtin. The defect causes the cytosine, adenine, and guanine (CAG) building blocks of DNA to repeat many more times than is normal (NINDS, 2016). Huntington’s disease is a progressive brain disorder that causes uncontrolled movements, emotional problems, and loss of thinking ability.…

    Huntington’s disease (HD) is a late-onset, usually between 35 and 50 years old, neurodegenerative disorder prevalent in 3-7 per 100,000 people of European ancestry1. The disease, inherited in an autosomal dominant pattern2, is characterized by motor disturbance, intellectual decline, and psychiatric manifestations3. The disease is difficult to detect at an early stage of an individual’s life since its symptoms appear in the third to fifth decade of life. To better understand the disease, investigations were done to identify the gene that is linked with the disease. Some of the common approaches to do this was linkage analysis and positional cloning often involving the use of polymorphic DNA markers to identify the best candidate gene that can…
