Friedreich Ataxia Research Paper
Friedreich ataxia (FRDA, OMIM 229300) is an autosomal recessive predominantly neurodegenerative disorder caused in most cases by mutations in the first intron of the frataxin (FXN) gene. This mutation drives to an increase in the number of GAA trinucleotide repeats within the first intron of the FXN gene on chromosome 9 (Campuzano, et al., 1996). The FXN gene is located on the long (q) arm of chromosome 9 at position 21.11., from base pair 69,035,563 to base pair 69,100,178 on chromosome

    Spinal muscular atrophy [SMA] is a disorder in which, you have a loss of motor neurons. Your muscle symmetry is often off. In addition, there is muscle weakness in your spinal cord. This occurs in a hard time sitting up and holding your head up on your own. It is just like when you are a newborn and you need a pillow to sit on the couch. A few major causes of SMA are loss of motor neuron cells or nerve cell. This mutation leads to a deficiency of motor neuron cells or nerve cells. The disorder SMA is tied to the gene "SMN1" and tied to chromosome 5. A few symptoms of this disorder are- difficulty breathing lack of oxygen, difficulty eating, floppy posture, small amount of movement, and all these symptoms will gradually get worse over time. All these symptoms are at about a mild level in the beginning.…

    ALX is caused by a mutation in the GFAP (Glial fibrillary acidic protein) gene on chromosome 17. Molecules of this protein bind together to form intermediate filaments which are used to support and strengthen cells. The mutation causes a structural alteration in GFAP which impairs the formation of normal intermediate filaments and they collect in cells called astrocytes. Astrocytes are non-neuronal glial cells that provide biochemical support to endothelial cells that form the blood-brain barrier, provide nutrients for nervous tissue and maintenance of extracellular ion balance etc. This leads to the formation of Rosenthal fibers in the astrocytes, abnormal clumps of GFAP. Therefore no nutrients are provided to the oligodendrocytes and as a result myelin is slowly degenerated.…

    The first step would be the stimulation whether it be air noises, water noises, music or someone coughing. The sound then travel to the outer ear where it is the reflected into the middle ear where it is amplified into the inner ear. The sound is then transferred through the viscous fluid in the cochlea. Inside the cochlea are tubes that are filled with fluid and hair cells. The hair cells are moved by the sound waves and become receptors for the primary auditory cortex. The cortex then processes the sounds into an interpretation. (University of Phoenix,…

    “Fatal familial insomnia is an inherited prion disease that affects the brain and other parts of the nervous system.”("Fatal Familial Insomnia." Fatal Familial Insomnia | Disease | Overview | Genetic and Rare Diseases Information Center [GARD]) Symptoms of this disease usually begin in midlife and can include insomnia that worsens with time, high blood pressure and vivid dreams. As previously stated, many people also develop ataxia with this disease. Ataxia is the inability to coordinate movements which causes a jerking motion or a gait in walking. In figure 6 it is shown that ataxia is a more common side effect when dealing with diseases that affect the Nervous System. FFI is caused by a mutation in the PRNP protein, and its function is unknown. Because Jane’s family history is consistent with autosomal dominant inheritance and the PRNP test came back positive, her diagnosis was made…

    Tay Sachs is caused by a mutation--a deletion of chromosome 15. The HEX A gene on this chromosome is responsible for creating the protein hexosaminidase A, which breaks down GM2, a component of nerve cells. When this builds up it is toxic and will cause cell death. The cause of this mutation is not known.…

    Amyotrophic lateral sclerosis is a motor neuron disease, degenerative and fatal in nature, that affects the worldwide population and more than 12,000 people in the United States alone. ALS remains idiopathic in nature, with only a small percentage of familial infection, and research into the causes and the progression of the disease has made little headway in the last 25 years, despite rising scientific interest. This article will provide a brief description of the known pathophysiology, diagnostic assessments, and treatment options currently available, as well as an insight as to what research will need to be completed to properly identify, treat, and possibly cure ALS in the early stages of the disease.…

    There are multiple ways that the ALS disease is passed down. FALS is generally autosomal dominant, which gives the affected person's children a fifty percent chance of having the disease if the parent had one normal gene and one mutated gene. ALS may also have an autosomal recessive pattern, which would require both parents to have a single mutated gene in order to pass the disease to the next generation. ALS is rarely passed down by an X-linked dominant pattern. To inherit ALS this way, the offspring ,if it is a female, needs to receive a mutated X chromosome from both parents. If the offspring is a male, only one X chromosome is needed to inherit the disease. FALS shows it's individuality by the many ways it transfers diseases from one generation in a family to the…

    Amyotrophic Lateral Sclerosis(ALS) is a specific disorder that involves the death of neurons that control voluntary muscles. ALS is characterized by stiff muscles, muscle twitching and gradually working weakness due to muscles decreasing in size. Also, Amyotrophic Lateral Sclerosis results in a difficulty speaking, swelling, and eventually not being able to breath on your Niown. ALS affects the brain and spinal chord muscles which leads to death or no control over these voluntary muscles.…

    Amyotrophic Lateral Sclerosis (ALS), otherwise known as " Lou Gehrig's Disease ", is a devastating disease that effects the nerve cells in the brain and spinal cord. French neurologist, Jean-Martin Charcot, first discovered the disease in 1869. Attention was not brought to the disease until 1939, when New York Yankees first basemen Lou Gehrig retired because of his diagnosis (4). Specifically referred to as a "neurodegenerative disease", ALS is the lack of nourishment to muscles (5). If you break "Amyotrophic" down into its latin meanings "A" means no, "Myo" is muscle, and "Trophic" means nourishment (6). It slowly eats way at the ability to eat, speak, walk, and breath, and will eventually lead to the victims death. ALS is the most common of five motor neuron diseases: botulism, tetanus, poliomyelitis, and spinal muscular atrophy. Motor Neurons run from the brain to the brain stem, connect to the spinal cord, and from the spinal cord they reach out to the corresponding muscles (5).…

    "We never think how great a gift is to think" (Gaskins). This is a quote that demonstrates the intensity of Alzheimer's Disease. Alzheimer's is a type of dementia that causes problems with memory, thinking, and behavior. I choose this topic to spread awareness about this cruel and deadly disease. I began my interest in Alzheimer's about three years ago, when I began volunteering for the association. My past involvements in the Alzheimer's Association began with a service event called "Walk to End ALZ 2k15." This was a marathon where all profits went to the Alzheimer's Association. Therefore, ever since this event, I've been hooked.…

    Multiple sclerosis is a disease in which your immune system attacks the protective covering of the nerves. The disease will disable the brain and the central nervous system. The main purpose of the disease is to attack the myelin; the myelin covers the nerve fibers. During the attack communication between the brain and the body is lost. In the end, the nerves will begin to be permanently damaged. The cause of the disease is yet to be found. Most common in people between ages fifty to sixty. Women are twice likely than men. More common when relatives have had history with multiple sclerosis. An infection like Epstein-Barr has been linked to MS. Race is factor; it is more common in white people than minorities. Smoking is a huge risk factor,…

    Huntington’s Disease is a homozygous dominant neurodegenerative disorder caused by a mutation in the HD gene. The mutation involves the basal ganglia, striatum and cerebral cortex parts of the brain and causes a CAG trinucleotide repetition. This repetition then proceeds to cause involuntary chorea, mood disorders, mental instability, and eventually leads to death. Since this is a relatively new discovery the Huntingtin gene is still mysterious in many ways to researchers. Many new discoveries have been made in regards to the damage that the mutation does to the brain but exactly how it does it eludes the science community.…
