Ataxia Telangiectasia

Ataxia Telangiectasia (A-T) is an inherited disorder that affects the nervous system, immune system, and other systems of the body. The disorder usually progresses before the age of 5 and it makes it difficult for coordination and causes delayed development of motor skills like walking, problems with balancing, and using your hands to grab items etc. A person may even have slurred speech, sway when they walk and wobble. These problems can affect a person as they get older and the effects can become worse as the person ages. Effects vary with each patient some may have severe immunodeficiency in which they cannot produce antibodies to fight off disease.

The ATM gene is involved with making proteins that help regulate the growth and division of cells. The ATM gene is also involved in the making of some of the bodies systems, immune, etc. Another essential role of the ATM gene is helping to detect DNA strands that are defective. When defective DNA strands are detected the ATM gene helps coordinate their repairs. Repairing the defective DNA in a cell helps maintain a cells genetic information. In A-T the ATM gene is disrupted in the making of proteins that regulate cell growth. These mutated genes do not repair DNA damage instead they allow for these defects to be spread into other cells. This allows for uncontrolled division and growth of cells which can lead to cancerous tumors. These mutations also allow for unwanted cell death which leads to the loss of important cells in the brain involved with coordination. People who are carriers of a mutated ATM gene are likely to develop one of the following cancers: breast, stomach, bladder, pancreas, lung, and …show more content…

Many patients affected by ataxia telangiectasia are expected to develop some type of cancer. The development of cancers is very likely in someone affected because the immune system is weakened by ataxia telangiectasia. Cancers such as stomach, brain, ovary, skin, liver, larynx, parotid gland, and breast are some of the possible developments. The life span of patients affected by the disease has been increasing throughout the years depending on mutations in a persons ATM gene. These mutations determine the severity of the symptoms seen in patients. Some patients with slowed progression of the disease have survived into their 50s.

There is currently no known cure for ataxia telangiectasia. Although there is no definitive cure research paths have been discovered to find a cure. These paths include gene therapy, the design of drugs to correct the function of altered proteins, and direct replacement of the functional protein. The disease can be controlled with therapy depending on what the person is affected with. Gamma-globulin injections can help supplement the weakened immune

Breaking down the disease “amyotrophic lateral sclerosis” word for word can help you understand how this disease affects someone. The word “Amyotrophic” comes from the Greek language. “A” means no, “myo” refers to the muscles, and “Trophic” means nourishment. This translates to “No muscle nourishment.” When a muscle has no nourishment it wastes away and cannot be used.

Cri-Du-Chat implies "Cry of the cat" in French. It gets its name from its most trademark highlight in infants were they contain a to a great degree specific deafening, weak, mewing cat like cry in the midst of right on time stages brought on by a sporadic change of the larynx that is regularly characteristic for the issue. This issue has various names to it as the Chromosome 5p-issue, Deletion 5p-issue, 5p short issue, Cat cry issue, and Monosomy 5p however most usually known as the Cri-Du-Chat Syndrome. Frequencies of this issue vary between 1 in each 20,000 - 50,000 live births general and as showed by the 5p less Society, around 50 to 60 adolescents are considered with cri du talk in the United States each year. Dr. Jerome Lejeune in 1963 depicted the issue as a hereditary inalienable issue associated with a midway cancelation of the short arm, or p area in chromosome 5 yet in %90 of patients the deletion is sporadic which infers it could happen subjectively and for it being basically natural is just not the circumstance.

Outline: According to Egans, ALS, or amyotrophic lateral sclerosis, is a disease that affects the nerve cells in the brain and spinal cord, “a progressive disease degeneration of both upper and lower motor neurons.” ALS prevents the nourishment of muscles, and when muscles are not fed the required nutrients, they atrophy. It hit’s areas of the spinal cord where the nerve cells that signal and control the muscles are located. As the area begins to die, it starts to scar or harden in that region. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body.

These general objections then form into more clear shortcoming or decay that may bring about a doctor to suspect ALS ("Amyotrophic"). The body parts indicating early side effects of ALS rely on upon which muscles in the body are influenced. Numerous people first see the impacts of the sickness in a hand or arm as they experience trouble with straightforward undertakings requiring manual ability. In different cases, manifestations at first influence one of the legs, and individuals experience clumsiness when strolling or running or they see that they are stumbling or staggering all the more regularly. At the point when side effects start in the arms or legs, it is alluded to as "appendage onset" ALS.

X linked or sex-linked ALD is a genetic disorder in which the impaired gene contains incorrect instructions for the enzyme responsible for the metabolism of very long chains of saturated fatty acids. The defective chromosome inhibits the function of the specific enzyme that breaks down VLCSFA, causing them to accumulate in the nervous system. The accumulation of VLCSFA causes the myelin sheath to strip away from the axon causing demyelination. Initial symptoms in Lorenzo affected with the childhood cerebral form of ALD include emotional instability, hyperactivity and disruptive behavior at school and home. He showed symptoms of visual loss, learning disabilities, seizures, poorly articulated speech, difficulty swallowing, deafness, disturbances

Pompe disease is an inheritable problem caused by the buildup in the cells of the simple sugar, Glycogen. While the underlying problem is the lack of a specific enzyme called acid alpha-glucosidase. When the cells start to have this build up, the organs that they make up start to not function properly. There is known to be three types of this disease that show how severe they are. This is best known through the age in which it first stands out in a person, the younger they are the more severe it will most likely be.

The infant may develop temporary muscle weakness and associated findings (i.e., transient neonatal myasthenia gravis). The passage of anti-acetylcholine receptor antibodies through the placenta to the unborn child during pregnancy may cause this condition to the infant. Some of the myasthenia gravis is inherited as an autosomal recessive, or more rarely, an autosomal dominant condition is described as congenital myasthenia gravis. The individual that inherits two copies of an abnormal gen for the same trait from each parent, the individual will have recessive genetic disorders. If the individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease but usually will not show symptoms.

Hao’s article is a better source than Martino’s for researchers to learn about the etiology of TS because it does an excellent job of highlighting the link between genetic mutations and TS. Hao points out that even though no specific mutations have be found to directly cause TS, genetic testing may enable identification that could lead to the development of new treatment strategies (Hao,
