Down syndrome has always been defined as a genetic condition. It is also known as Trisomy 21, and it is the most common genetic cause of intellectual disability. Nelson and Gibbs (2004) said “Trisomy results from sporadic nondisjunction of chromosome 21 leading to three copies of the smallest human chromosome”. Trisomy 21 is the cause of about ninety-five percent of observed Down syndrome. Most of the nondisjunction comes from the maternal gamete while a very small amount of the nondisjunction comes
Down syndrome is a genetic disorder, associated with the presence of an extra chromosome. Downs is characterized by mild to severe mental impairment, weak muscle tone, shorter stature, and a flattened face. Down syndrome is not a very common disease, one in every 691 children are born with Down syndrome. The disability is an illness that people are born with and is not contagious. Most people with Downs have a life expectancy of about 40 or 50 years of age. They only live for that short amount of
Down Syndrome Down's Syndrome, it is one of the most frequently occurring chromosomal abnormalities found in humans effecting people of all ages, races and economic levels. It is a chromosomal anomaly in cell development that results in a person being born with forty-seven chromosomes instead of the normal forty-six chromosomes. People with Down syndrome may have mild to severe learning disabilities and physical symptoms, which include a small skull, extra folds of skin under the eyes, and a
has a genetic disorder called Down Syndrome (“National Down Syndrome Society,” n.d.). Within a matter of minutes parents learn that children with Down Syndrome can also have a variety of other conditions and disorders, will not develop in the same way that other children do, and may even have a shorter life span. However, children with Down Syndrome are happy-go-lucky children with a kind disposition and a wonderful personality. Also known as Trisomy 21, Down Syndrome does not mean the end of a child’s
What most people don’t know about Down syndrome is that they can live normal lives and with much therapy and the right education people with the condition can live on their own, have a career, and get married. (Linda Crnic Institute for Down syndrome.) However, helping them is crucial to be able to do everyday things, such as cooking, cleaning, and taking care of personal hygiene. With learning these life skills that most adults learn over time, they need more help and people to work with them.
Down syndrome was discovered in the 1800’s by a man named John Langton Down. Down syndrome1 is a condition that occurs in the chromosomes. The syndrome affects the intellectual ability of the person effected, their facial appearance and causes hypotonia2. Children born with this usually experience different types of birth defects. These birth defects can include heart defects and intestine blockage. People with Down syndrome are also at a high risk of developing other medical conditions. Some
or partial extra copy of chromosome 21 present; these individuals have Down Syndrome (National Down Syndrome Society). Down Syndrome is a genetic disorder that most people know very little about. Since Down Syndrome is something that very few people know much about, this paper will include a lot of information about the disorder that is not well known to the general public. In this paper I will discuss what exactly Down Syndrome is and provide background information and history, describe how and when
Down syndrome was named after John Langdon Down, the British doctor who discovered the syndrome in 1866. The syndrome was not linked to chromosome twenty- one until 1959 by Jerome Lejeune. Down syndrome, the most common genetic condition, occurs in one out of six-hundred and ninety-one kids in the United States. This syndrome is caused by an extra number twenty-one chromosome, also known as trisomy twenty-one. In most cases it is caused by nondisjunction; which is sister chromatids of the twenty
Children with Down Syndrome Down syndrome affects many people in this world. Not only does it affect the person diagnosed as Downs, but it also affects their family and everyone around them. There are physical characteristics that help you identify somebody with Downs. There are also some health concerns that you need to worry about. In this essay I will give you a clearer understanding of what Downs syndrome is, and what it means to have Downs. Down syndrome can be caused for three different
Rodriguez 1 Mrs. Rioux English 1A 5/23/2014 Down Syndrome Students In our grade school years we were taught that kids with disabilities were special. We should treat them the same way we would want to be treated. In school everyone thought they all looked the same and acted the same. We were young and did not know any better. These kids were the special kids and they had a disability called Down Syndrome. In my life I have had two friends with Down Syndrome. One of their names was Kimmy. I met Kimmy
000 babies born in the United States each year is born with Down syndrome. It affects an equal number of male and female babies” (Johnson P. A. 2014). Down syndrome is a genetic disorder that found across the world, however it is more prevalent in the United States. The cause of the disorder roots to the paring of the human chromosomes. A normal human receives 23 pairs of chromosomes, each pair coming from mother and father. In Down syndrome most people affected have an abnormal cell division of the
Down syndrome, which is also called Trisomy 21, is a condition in which extra genetic material causes delays in the way a child develops mentally and physically. Down syndrome is named after British doctor John Langdon Down. He first prescribed the condition in 1887. In 1959, an extra chromosome was identified as the cause. Down syndrome features and problems can vary from child to child. Some children need a lot of medical attention and others lead healthy lives. In the United States, Down syndrome
Introduction About Down Syndrome There are many disorders or syndromes that cause people to behave and act differently than others. Out of all these syndromes, I picked one of them. This is a very rare syndrome and an estimate of 4% of children in the U.S. have it. It is known as the translocation down syndrome. Translocation down syndrome is a type of down syndrome caused by rearranged chromosome material. A child with translocation down syndrome has 3 #21 chromosomes instead of the two pairs.
2014 Down Syndrome It is believed that people with Down Syndrome has been around for a while. In 1959 Professor Jérome Lejeune proved that Down's syndrome is a chromosomal irregularity.Parents in that time were ashamed of their children with disabilities.In 1944 kids with disabilities did not have the right to have an education. Not until 1971 it was recognized that it should be legal for people with learning disabilities to get an education.Life expectancy for people with Down syndrome has heightened
is also important to understand how children with Down syndrome develop and interact in a classroom in order to provide a better education for them. This paper will explain to the reader the different methods of successfully interacting with children with Down syndrome and creating a positive relationship among the classroom, which is the topic that I will be covering today. Not only will I cover how to interact with children with Down syndrome, but
‘’Down syndrome is a type of mental retardation caused by extra genetic material in chromosome 21’’(1). In the beginning, children with Down syndrome were referred as “mongoloids” because they looked like people from Mongolia but, the term was changed to Down’s syndrome. Down’s Syndrome named after John Langdon Down, the man who first described it (2). Down syndrome due to a genetic cause and it has more than one type and characteristics. Every cell in the human body contains genetic material
Down Syndrome: Critically analyze the effects of Down syndrome on people and the support that is available Introduction: An individual who has Down syndrome can be recognized as different from others since he or she have different physical features, but the question is, what causes individuals to have deformed face, little different features than someone who does not have Down syndrome? The reason some individuals are born with Down syndrome is because of an extra chromosome, this chromosome, which
Down syndrome also known as “trisomy 21” is a genetic condition in which a child is born with an extra chromosone which causes certain features and delays in development. In sexual reproduction (meiosis) the new cell will have half of the mothers chromosones 23 and half of the fathers chromosones 23 to make a total of 46 (23 pairs) in the new cell (zygote). In a child with Down Syndrome they will have an extra chromosone 21 making a total of 47 chromosones. There is no specific reason why this
Down's Syndrome Down's syndrome is a genetic condition involving an extra chromosome, this change occurs around the time of conception. A person with Down's syndrome has forty-seven chromosomes instead of the usual forty-six. A relatively common genetic disorder, Down's strikes 1 out of 600 babies. In 95 percent of all cases, the disorder originates with the egg, not the sperm, and the only known risk factor is advanced maternal age-at age 35, a woman has 1 chance in 117 of having a baby with Down's;
Down syndrome is a genetic disorder in which a person is born with an extra copy of chromosome 21. There are three genetic variations that cause Down syndrome: Trisomy 21, Mosaic Trisomy 21 or Translocation Trisomy 21. There are many ways in which theses disorders affect the body. Trisomy 21 occurs when an egg or sperm comes in with an extra copy of chromosome 21, then, once an embryo is formed and starts to develop, the chromosome is replicated in every single cell of the embryo. Trisomy 21 is
