Muscular dystrophy refers to, not one, but a group of muscle diseases. These diseases have three features in common: they are hereditary; they are progressive; and each causes a characteristic and selective pattern of weakness. Duchenne muscular dystrophy (DMD) is the most prevalent and severe childhood form of this group of diseases. Each form of muscular dystrophy is caused by a defect in a specific gene. In 1986, scientists discovered exactly which piece of genetic material is missing in Duchenne
“Dystrophy,” originally coming from the Greek “dys,” which means “difficult” or “faulty, and “trophe,” meaning “nourishment” holds the interpretation “poor nutrition.” Today we know poor nutrition is not the cause of Muscular Dystrophy (“Myotonic Dystrophy”). Muscular Dystrophy is a genetic disorder that affects between 500-600 newborns each year in the US (Statistics on Muscular Dystrophy). In general, this disorder weakens your skeletal muscles, and eventually they degenerate. Muscular Dystrophy
Dan Evans Lindenwood University Genetics November 25, 2012 Introduction Myotonic dystrophy, type 1, is a genetic disorder which is linked to chromosome number 19 in humans. The dystrophia myotonica protein kinase gene is located on the q arm of the chromosome at the locus of 13.32. It is an autosomal dominant disorder, which means that the individuals that are affected by this disorder and contain at least one dominant allele for the dystrophia myotonica protein kinase gene. The disorder
According to the MediLexicon Medical Dictionary, muscular dystrophy is defined as a general term for a number of hereditary, progressive degenerative disorders affecting skeletal muscles, and often other organ systems (Staff). Basically what that means is that muscular dystrophy is a genetic disorder that is passed down that affects the skeletal muscles and other organs by slowly breaking them down. Since it is genetic, it is not contagious and you cannot catch it from someone who has it. MD weakens
the age of 12 and won't live past the age of 20. This has become a reality for many parents as they find out that their child has a form of muscular dystrophy. This particular type of muscular dystrophy is referred to as Duchenne Muscular Dystrophy, which is a genetically inherited disorder that is the most common and severe of all muscular dystrophies. It is found in 1 of every 3,500 males and is characterized by progressive muscle wasting. It is caused by the lack of dystrophin, which is a protein
Duchene or Becker muscular dystrophy. (“Data & Statistics,” 2012 April 6) Muscular dystrophy is a group of genetic diseases defined by muscle fibers that are unusually susceptible to damage. There are several different types of muscular dystrophy some of which shorten the affected person’s lifespan. (“Muscular dystrophy: Types and Causes of each form,” n.d.) There is a long history of the disorder but until recently there wasn’t much knowledge of the cause. (“Muscular Dystrophy: Hope through Research
explanation of what Muscular Dystrophy is and a general information paragraph over each type of the major muscular dystrophies today. What is Muscular Dystrophy? Muscular dystrophy (MD) is a genetic disorder that weakens skeletal muscles, the muscles that enable the human body to move. People with muscular dystrophy have missing or incorrect information in their genes, which prevents them from making the proteins they need for healthy muscles. Due to fact that muscular dystrophy is genetic, it is not contagious
Muscular Dystrophy (MD) is a disease that weakens the musculoskeletal system and affects the ability to move. MD also affects groups of muscles. In the 1860’s it was described that boys were progressively growing weaker, losing the ability to move and died at an early age. A decade after the first description a French, neurologist named Guillaume Duchenne gave account for thirteen boys with the most common and severe forms of Muscular Dystrophy. MD is being caused by a mutation of a gene within the
muscular dystrophy has many forms and therefore symptoms can vary between the variations. Overall symptoms include the weakening of skeletal muscles and the defect and death muscle tissues. Duchenne muscular dystrophy is the most common and affects young boys such as Eddie. Eddie is an 11 year old boy and has been diagnosed with Duchenne muscular dystrophy. The symptoms appeared at the age of 5 and had led to the weakening of his leg and arm muscles and the eventual need of a wheelchair. Some of
A muscular dystrophy is a group of diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement. This disease will occur when one just one of the thousands of genes that aid in programming proteins critical to muscle integrity is mutated. There are some types of muscular dystrophies that affect the heart, gastrointestinal system, endocrine system, spine, eyes, brain, and other organs. This disease may cause a serious respiratory and cardiac disease
Duchenne muscular dystrophy (DMD) is a form of a rapidly progressive muscular dystrophy that is the utmost deadly disorder diagnosed in childhood effecting children. DMD can occur as early as infancy and as late as age six. The disorder affects mostly males, because the Duchenne gene is located on the X-chromosome. DMD happens across all races and through rare, females can be diagnosed. The mutated DMD gene is typically inherited in a recessive manner, however it often occurs in families with
Duchenne's muscular dystrophy, also known as psuedohypertrophic muscular dystrophy, is a typical sex-linked disorder in which the muscles degenerate throughout a person's life. It literally means "faulty nutrition of the muscles." Muscular Dystrophy has no cures, and this particular type of muscular dystrophy affects only males. One in 3,500 baby boys are born with this disorder and survival is rare beyond the early 30s, death is usually caused by a respiratory disease. (ygyh.org) Duchenne's
Emery-Dreifuss muscular dystrophy Emery-Dreifuss muscular dystrophy is a rare form of muscular dystrophy characterized by early onset contractures of the elbows, achilles tendons and post-cervical muscles with progressive muscle wasting and weakness It is also associated with heart complications like cardiomyopathy and arrhythmia which in both cases can lead to death. Cardiomyopathy is a heart disease which affects the muscles of the heart. In cardiomyopathy is muscles get rigid, enlarged or thick
characterized by progressive muscle degeneration and weakness. It is one of nine types of muscular dystrophy. DMD is caused by an absence of dystrophin, a protein that helps keep muscle cells intact. Symptom onset is in early childhood, usually between ages 3 and 5. The disease primarily affects boys, but in rare cases it can affect girls. What are the symptoms of DMD? Muscle weakness can begin as early as age 3, first affecting the muscles of the hips, pelvic area, thighs and shoulders, and later

Duchenne Muscular Dystrophy, commonly referred to as DMD, is a life threatening disease. There are many different forms of muscular dystrophy, Duchenne being one more serious. DMD begins to show at a young age. This particular form of muscular dystrophy is mostly found in males. Duchenne is carried by the mother on the X chromosome but often, the event of having this disease is just a “fluke.” Duchenne Muscular Dystrophy is a deadly and unfortunate disease but new research that is being done may
• Duchenne Mascular Dystrophy (DMD): Physiological Basis of disease: DMD is the commonest and most serious form of the dystrophies. The gene responsible for dystrophin which, when absent, causes DMD. Amount of dystrophin correlates with the severity of the disease (i.e., the less dystrophin present, the more severe the phenotype). Since the gene is on the X chromosome, it primarily affects males, and females who are carriers have milder symptoms ( www.nlm.nih.gov/medlineplus/ency/article/000705
Duchenne Muscular Dystrophy last week. I share my condolences for your family, as this must be a tough time for the both of you. In this letter there will be information regarding what Duchenne Muscular Dystrophy is, how it is caused, how it is treated, and the daily life for those affected with Duchenne Muscular Dystrophy and their family members. Muscular Dystrophies are genetic disorders that are distinguished by degenerative muscles and weakness in the muscles. Duchenne muscular dystrophy is a dominant
Introduction to Duchenne Muscular Dystrophy Duchenne Muscular Dystrophy is caused by the mutation of the necessary muscle protein dystrophin that occurs on the X chromosome, and due to the way the disease is inherited it usually affects males. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father. If their X chromosome has a DMD gene mutation, they will have Duchenne muscular dystrophy. According to the US National Library of Medicine (www
Muscular Dystrophy is type of genetic disorder consisting of 30 characterized genetic diseases. Essentially, Muscular Dystrophy reduces the strength of the muscles in your body until eventually they degenerate and lose all function. Each type of this rare disease varies in its affects, symptoms, and severities. However they are all commonly caused by dissimilar genes accompanied by imperfections. Muscular Dystrophy was first historically recorded in 1830, by Sir Charles Bell, when he composed a paper
