Down syndrome as a cognitive disorder Down syndrome (DS) is relatively well known as a genetic disorder to the general public and children with this syndrome form one of the most readily identifiable groups of children with moderate to severe learning difficulties. It has been over 130 years since Langdon Down first described DS and 30 years since the presence of the defining extra copy of chromosome 21 was identified by Lejeune and…

Down syndrome is a birth defect caused by a genetic disorder that affects 350,000 people in the United States. It is caused by abnormalities in the genes and is not inherited, meaning that parents do not pass this onto their children. Genetics is the study of heredity or how certain traits are passed from parents to their children. Genes are the basic unit of heredity. Cells are the building blocks of your body and each one of us has more than 100 trillion cells. Our genes are located in chromosomes…

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…

Down syndrome is a genetic disorder that begins to develop at the cellular level after conception. All the cells in the human body contain a center, called a nucleus, in which genetic code of each human being is stored. This genetic material, known as genes, carries the codes responsible for all our inherited characteristics from the mother and the father. Genes are grouped along rod-like structures called chromosomes. The nucleus of each cell normally contains 23 pairs of chromosomes, half of which…

of down syndrome? According to many National Down Syndrome Society within the United States, Down syndrome has occurred one out of eight hundred births. It is the most frequent form of mental retardation and characterized by well-defined events and distinctive features. It’s a lifelong disorder caused by a genetic defeat that’s none curable. It takes people with patients and kind hearts to care for people with Down syndrome disorder. History In the late nineteenth century John Langdon Down, an…

Down syndrome is a genetic disorder most commonly caused by extra copies of chromosome 21. It occurs randomly during cell division in fetal development. This paper will discuss general information on Down syndrome, which will include the discovery of syndrome, the types and causes, the risk factors. Furthermore, this paper will also discuss the sign and symptoms, diagnosis and treatment. General background Down syndrome is a genetic disorder occurs in every individual regardless of gender, ethnicity…

Down Syndrome: An Informative Essay Down Syndrome is the name for babies born with a disorder related to their chromosomes. It is caused when meiosis occurs and an error occurs in the cells development. The reason for this defect is often because the parent is over 40 or for some other reason their meiosis is not "Up to par." The actual defect is an extra chromosome is developed during cell development. The abnormal development results in 47 chromosomes rather than the usual…

Having a Down syndrome is such a difficult situation for an individual to have. They have slow physical and mental capabilities that lead them to discrimination. Physical features of having a Down syndrome. Including flattening of the head; slanting of the eyelids; a gap between the first and the second toes; a depressed nasal bridge; relatively small ears, mouth, hands and feet; short stature; decreased muscle tone and loose ligaments among others.

Down Syndrome They used to be called "Mongoloids," an ethnic insult coined by John Langdon Down, an English physician during the nineteenth century. But now they are known as people, individuals with a condition known as Down syndrome. (3). It wasn't until the 1960s that Jerome Lejeune and Patricia Jacobs discovered the cause of Down syndrome (also called trisomy 21). But with technological advancements within the scientific community, more and more information has been gathered about the…
