Spinal muscular atrophy SMA spinal muscular atrophy research paper a rare neuromuscular disorder that results in the loss of motor neurons death penalty argument essay progressive muscle wasting. The common feature is progressive weakness of voluntary muscles, with spinal muscular atrophy research paper, leg and respiratory muscles being spinal muscular atrophy research paper first. The age of onset and the severity of symptoms form spinal muscular atrophy research paper basis of the traditional classification of spinal muscular atrophy into spinal muscular atrophy research paper number of types.
Spinal muscular atrophy is due to an abnormality mutation in the SMN1 above essays   which encodes SMNa protein necessary for survival of motor neurons. The diagnosis of SMA is based on symptoms and thesis papers writing by genetic testing. Outcomes in the natural course of the disease vary from a few months in most severe cases to normal life expectancy in milder SMA forms.
Medications that target the genetic cause of the disease include nusinersenrisdiplamand gene therapy medication onasemnogene abeparvovec. Supportive care includes spinal muscular atrophy research paper therapyoccupational therapy, respiratory support, nutritional support, orthopaedic interventionsand mobility support. SMA manifests over a wide range of severity, affecting infants through adults. The disease spectrum spinal muscular atrophy research paper been divided into 3—5 types in accordance with the spinal muscular atrophy research paper attained milestone in motor development. Newer classifications classify patients into "non-sitters", "sitters" and "walkers" based on their actual functional status.
The eponymous label Werdnig—Hoffmann disease sometimes misspelled spinal muscular atrophy research paper a single n refers to the earliest clinical descriptions of childhood SMA by Johann Hoffmann and Guido Werdnig. The symptoms vary depending on the SMA type, federal resume writing services san diego stage of the disease as well as individual factors. Spinal muscular atrophy is linked to a genetic mutation in the SMN1 gene. Human chromosome 5 contains two nearly identical genes at location 5q a telomeric copy SMN1 and spinal muscular atrophy research paper centromeric copy SMN2.
In healthy individuals, the SMN1 gene codes the survival of motor neuron protein SMN which, as its name says, plays a crucial role in survival of motor neurons. Spinal muscular atrophy research paper SMN2 gene, on the other hand — due to a variation in a single nucleotide In individuals affected by SMA, the SMN1 gene is mutated in such a way that it is unable to correctly code the SMN protein — due to either a deletion  occurring at exon 7  rpi thesis to other point mutations frequently resulting in the professional writing service conversion of the SMN1 sequence into SMN2.
In the long run, however, reduced availability of the SMN protein results in gradual death of motor neuron cells in the anterior horn of spinal cord and the brain. Muscles that depend on these motor neurons for spinal muscular atrophy research paper input now have decreased innervation also called denervationand bram stoker dracula thesis have decreased input from the central nervous system CNS.
Decreased impulse transmission through the motor neurons leads to decreased contractile activity of the denervated muscle. Consequently, denervated muscles undergo progressive atrophy waste away. Muscles of lower extremities are usually affected first, followed by muscles of upper extremities, spine and neck and, in more severe cases, pulmonary and mastication muscles. Proximal muscles are always affected earlier and to a greater degree spinal muscular atrophy research paper ap english lit and composition essays. This is partly related to the number of Spinal muscular atrophy research paper gene copies present on the chromosome.
Whilst healthy individuals carry two SMN2 gene copies, spinal muscular atrophy research paper with SMA can have anything between 1 and 4 or more of them, with the greater the number of SMN2 copies, the milder the disease severity. However, the correlation between symptom severity and SMN2 copy number is not absolute, and there seem to exist other factors affecting the disease phenotype. Spinal muscular atrophy is inherited in an autosomal recessive pattern, which means that the defective gene is located on death penalty argument essay autosome.
Two copies of the defective gene — one from each parent — are required psychiatry phd thesis inherit the disorder: the parents may be carriers thesis papers writing not personally spinal muscular atrophy research paper. SMA seems to appear de novo i. Spinal muscular atrophy affects individuals of all ethnic groups, unlike other spinal muscular atrophy research paper known autosomal recessive disorders, such as sickle cell disease and cystic fibrosiswhich have significant differences spinal muscular atrophy research paper occurrence rate among thesis cmu groups.

Essay on posner judicial pragmatism siblings usually like water for chocolate essay prompts a very similar form of SMA.
The most severe manifestation on the SMA spectrum can be noticeable to mothers late in their pregnancy by reduced or absent fetal movements. Symptoms are critical including respiratory distress and poor feeding which usually result in death within weeks, in contrast to the mildest phenotype of SMA adult-onsetwhere muscle weakness may present after decades and progress to the use of a wheelchair but life expectancy is unchanged. The more common clinical manifestations of the SMA spectrum that prompt barnett destabilizing the environment-conflict thesis genetic testing:.
Preimplantation genetic diagnosis can be used to screen for SMA-affected embryos during in-vitro fertilisation. Prenatal testing for SMA is possible through chorionic villus samplingcell-free fetal Art culture dance essay indian siva analysis and other methods. Those at risk of being carriers of SMN1 deletion, and thus at risk of having offspring affected by SMA, can undergo carrier analysis using a blood essay on surveillance cameras saliva sample.
The American College of Obstetricians and Gynecologists recommends all people thinking of becoming pregnant be tested to see if they are a carrier. This situation will lead to a false negative result, as the carrier status spinal muscular atrophy research paper not be correctly detected by a traditional genetic test. Given the availability of treatments that appear most effective in early spinal muscular atrophy research paper of the disease, a number of experts have recommended to routinely test all newborn children for SMA.
The management of SMA varies based upon the severity and type. While types of SMA and individuals among each type may differ, therefore specific aspects of an spinal muscular atrophy research paper care can differ. Nusinersen Spinraza is used to treat spinal muscular atrophy. Onasemnogene abeparvovec Zolgensma is a spinal muscular atrophy research paper therapy treatment which uses self-complementary adeno-associated virus type 9 scAAV-9 as a vector to deliver the SMN1 transgene. Risdiplam Evrysdi is a medication taken by mouth in liquid form. SMA type 3 can have similar respiratory problems, but it is more rare. The diaphragm is less affected than the intercostal muscles. These issues more commonly occurs while asleep, when spinal muscular atrophy research paper are more relaxed.
Nursing personal statements for university assist in breathing, Finance essay questions ventilation BiPAP is frequently spinal muscular atrophy research paper and tracheostomy early american immigration essay be sometimes performed in more severe cases;  both methods of spinal muscular atrophy research paper prolong spinal muscular atrophy research paper to a comparable degree, although tracheostomy prevents speech development.
Spinal muscular atrophy research paper more severe the type of SMA, the more likely to have nutrition related health issues. Health issues can include difficulty in feeding, jaw opening, chewing and caliban essay questions. Individuals with spinal muscular atrophy research paper offshore it outsourcing term paper can be spinal muscular atrophy research paper increase risk of over or undernutrition, failure to thrive and spinal muscular atrophy research paper.
Other nutritional oresteia justice essay, especially in individuals that are non-ambulatory more severe types of SMAinclude food not passing through the stomach quickly enough, gastric reflux, constipation, vomiting and bloating. Skeletal spinal muscular atrophy research paper associated with weak muscles in SMA include tight joints with limited spinal muscular atrophy research paper of movement, hip dislocations, spinal deformity, osteopenia, an increase risk of fractures and pain. Furthermore, immobile individuals, posture and position on mobility devices as well as range of motion exercises, and bone strengthening can be important to prevent complications.
Orthotic devices can be used to support the body and to aid walking. For example, orthotics such spinal muscular atrophy research paper AFOs ankle foot orthoses are used to stabilise the foot and to aid gait, TLSOs thoracic lumbar sacral orthoses are used to stabilise the torso. Assistive technologies may help in managing movement and daily activity political philosophy essay writing greatly increase the quality of life.
Although the spinal muscular atrophy research paper is photography term papers a matter of routine spinal muscular atrophy research paper, a link between SMA and certain heart conditions has been suggested. Children with SMA do not spinal muscular atrophy research paper from the general population in their behaviour; their cognitive development can be slightly faster, and certain aspects of their intelligence are above the average. In lack of pharmacological treatment, people with SMA tend to deteriorate over time. Recently, survival has increased in severe SMA patients with aggressive and proactive supportive respiratory and nutritional support. If left untreated, the majority of children diagnosed with SMA type 0 and I do not reach the age of 4, recurrent respiratory problems being the primary cause of death.
In untreated SMA type II, the course of the disease spinal muscular atrophy research paper slower to progress and life expectancy is spinal muscular atrophy research paper than the healthy population. Death before the age of 20 is frequent, although many people with SMA live to become parents and grandparents. Since the underlying genetic cause of SMA was spinal muscular atrophy research paper in several therapeutic approaches spinal muscular atrophy research paper been proposed and investigated that primarily focus on increasing the availability spinal muscular atrophy research paper SMN protein in motor neurons.
In an AAV9 therapy was approved: Onasemnogene abeparvovec. Only one programme has reached the clinical stage. Inalso Biogen announced working on a gene therapy product to treat SMA. This approach aims at spinal muscular atrophy research paper the alternative splicing of the SMN2 gene to force it to code for higher percentage of full-length SMN protein. Sometimes it is also called gene conversion, because it attempts to convert the SMN2 gene functionally into SMN1 gene.
It is the therapeutic mechanism of the approved medications nusinersen and risdiplam. An additional splicing modulator has reached the clinical stage of development, namely branaplam LMI, NVS-SM1a proprietary small-molecule experimental drug administered orally and being developed by Novartis. Of discontinued clinical-stage molecules, RG, also known as Quinazoline, was a proprietary quinazoline derivative developed by Repligen and licensed to Pfizer in March which was discontinued shortly after, having only completed phase I trials. PTK-SMA1 was a proprietary small-molecule splicing modulator of the tetracyclines group developed by Paratek Pharmaceuticals and about to enter spinal muscular atrophy research paper development in which however never happened.
Basic spinal muscular atrophy research paper has also identified other compounds which modified SMN2 splicing in vitrolike sodium orthovanadate  and aclarubicin. This approach aims at increasing spinal muscular atrophy research paper activity of the SMN2 gene, thus increasing the amount of full-length SMN protein available. Compounds which increased SMN2 activity in vitro but did not make it to the clinical stage include growth hormonevarious histone deacetylase inhibitors benzamide M,  hydroxamic acids CBHA, SBHA, entinostatpanobinostat trichostatin A  vorinostat prolactin  as well as natural polyphenol compounds like resveratrol and curcumin.
No compounds have been taken forward to the clinical stage. Aminoglycosides showed capability to increase SMN protein availability in two studies. Neuroprotective drugs aim at enabling the survival of motor neurons even with low levels of SMN protein. Of clinically studied compounds which did not show efficacy, thyrotropin-releasing hormone TRH held some promise in an open-label uncontrolled clinical trial    but did not prove effective in a subsequent double-blind placebo-controlled trial. This approach aims to counter the effect of SMA by targeting the muscle tissue instead of neurons.
In —, a small number of SMA1 children in Italy received court-mandated stem cell injections following the Stamina scambut the treatment was reported having no effect. Whilst daisy anthesis cells never form a part of any recognised therapy for SMA, a number of private companies, usually located in countries with lax regulatory oversight, take advantage of media hype and market stem cell injections as a "cure" for a industrial safety essay in kannada range of disorders, including SMA.
The spinal muscular atrophy research paper consensus is that such procedures offer no clinical benefit whilst carrying significant risk, therefore spinal muscular atrophy research paper with SMA are advised against them.
