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
Down syndrome; what is it and how does it affect the people who have it? Roughly 1 in 800 infants born in Canada are affected by Down syndrome. Down syndrome, also called Trisomy 21, is a chromosomal disorder that is caused by an extra genetic material in the individual. It delays the way an individual develops both mentally and physically. Down syndrome cannot be prevented but it can be detected before birth. At the time of conception an infant inherits genes from its parents in the form of 46 chromosomes
Down Syndrome Down syndrome is the most common genetic disorder among children. 1 out of every 1,000 is diagnosed with what is more commonly known as DS (Leshin, 2000). DS was first observed in 1866 by John Langdon Down, an English physician. However, only speculation existed on what caused this debilitating disease. In 1959, Jerome Lejeune and Patricia Jacobs discovered the true cause. It is trisomy of the 21st chromosomes that causes DS and the debilitating characteristics along with it (Leshin
Paper Down syndrome is a birth defect that happens before birth. Down syndrome is caused by a defect in genes, because of this defect in genes it causes an error in cell division, thus resulting in an extra copy of chromosome twenty-one. In the year of 1866 was when the first case of Down syndrome was diagnosed. At the time, many people were familiar with the characteristics that occur due to Down syndrome but It wasn 't until, English physician John Langdon Down, described Down syndrome as a disorder
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
occurs, chromosomes may be lost, left behind, or too many may be passed on, resulting in the birth of a child with a genetic or congenital defect or disease. One of the most common of these genetic disorders is Down syndrome. This disorder takes its name from Dr. Langdon Down, who was the first to describe it formally, in 1866. Down syndrome is a condition marked by abnormal physical and mental development that is caused by a genetic defect. This genetic defect is caused by an extra chromosome. People
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
Down Syndrome Trisomy 21 is caused, as the name suggests, by the triplication of the 21st chromosome. Genes which, simplified, contain the blueprints for our cellular structure, are grouped along rod-like structures called chromosomes. Normally, the nucleus of each cell contains 23 pairs of chromosomes, half of which are inherited from each parent. In Down syndrome (DS), however, the cells usually contain not 46, but 47 chromosomes. This excess genetic material, in the form of additional
Alzheimer and Down's Syndrome Down?s Syndrome, Trisomy 21, or Mongolism is one of the most common causes of mental retardation. The majority of Down?s Syndrome patients have a moderate retardation although it can range from mild to severe. Trisomy 21 occurs in about 1 in 800 live births. This incidence increases markedly as the age of the mother increases over 35. The prevalence in children born to young mothers is 1 in 1000, while it increases to almost 1 in 40 in children born to mothers over
Down syndrome is a variance in chromosome 21 that manifests with cognitive delay, muscle hypotonia, characteristic facies, and short stature. (Glanzman, 2015 & Powell-Hamilton, 2012) The genetic disorder was named after the Physician John Langdon Down, who had originally in 1866 labeled those with the genetic abnormality as “Mongoloids”; Down indicated his choice of term for the children because of their appearance was allegedly similar to those from Mongolia and at the time it was believed that
