Some people wonder what Down syndrome is. How it is caused, and how it is treated. The causes and effects of Down syndrome is when there is an extra 21St chromosome. The effects include some birth defects and health problems. The physical features are different from someone without Down syndrome.
What is Down syndrome? It is a chromosomal disorder caused by an error in cell division that results in an extra 21st chromosome (Crosta). Down syndrome causes problems with a person’s physical growth that vary by how bad it is. This disease can develop either before or after a child is born. Less than 1,000 pregnancies for mothers less than 30 years of age result in a baby with Down syndrome. For mothers who are 44 years of age, about 1 in 35 pregnancies results in a baby with Down syndrome (Crosta). The only way to have a child with Down syndrome is determined by the mother’s age. 75-80% of babies that have Down syndrome are born to younger mothers. It is believed that a younger woman usually has more children verses an older woman (Crosta).
What causes Down syndrome? Robertsonian translocation occurs when part of chromosome 21 breaks off during cell division and attaches to another chromosome (usually chromosome 14) (Crosta). There are 46 chromosomes in the body. 23 are from the mother and 23 are from the father. When there is another copy or a half copies of chromosome 21, you will have a child with Down syndrome. The most common type of Down syndrome is Trisomy 21. It is where the body has 47 Chromosomes instead of 46 (Crosta). Trisomy 21 is caused by a problem in the cell division called non-disjunction; it leaves a sperm or an egg cell with an extra copy of chromosome 21. 95% of Down syndro...

...hromosome. Most pregnancies for a mothers 40 years of age or older will have a higher risk of having a Down syndrome child. The older the mother is, the more of a chance she will have for her baby to be diagnosed with Down syndrome. The effects of Down syndrome are ear infections, Leukemia at an early age, different physical features than a person without it, and birth defects. There are things to help a person deal with the disease by going to therapy and learning things to help their physical abilities.

- Down syndrome is congenital condition in which there is presence of an extra 21st chromosome. In every human being there is an small yet intricate hub that holds genetic material called the nucleus. This genetic material is carried by genes and each and every one of our main characteristics or traits is grouped together next to an imperative structure called a chromosome. When an individual has an extra 21st chromosome, they experience a disorder in which the person experiences “intellectual disability, a characteristic facial appearance, and weak muscle tone (or hypotonia) in infancy....

- Down Syndrome is one of the most common forms of genetic birth defects. Usually, children born with this condition have some degree of mental retardation, as well as characteristic physical features. Many of these children also have other health problems. Each year in the United States alone, approximately one in every 800 to 1,000 newborns has Down Syndrome. This equates to approximately 5,000 children born with Down Syndrome every year. In the United States today, Down Syndrome affects approximately 350,000 people.... [tags: Down syndrome, Chromosome]

- Humans are more like the X-Men then they have ever dreamed possible. Studies show that each and every single human in our species have more than two hundred mutations weaved in and out of our DNA. A genetic mutation is a perpetual change in the DNA sequence that makes up a gene. These mutations can occur in two different ways; they can be acquired during one’s lifetime or they can be inherited from one’s biological parents. Some mutations are absolutely harmless; these are the mutations that take up most of the typical human’s body.... [tags: mutation, chromosomes, health]

- In today’s society more women need to be aware of the disorder that is becoming more common every year. A study shows that there are about 6,000 diagnoses of Down Syndrome each year in the United States("National association for Down syndrome"). One in every 800 babies is born with Down Syndrome (Marsh). This is a rise from the previously reported statistic of 1 in every 733, as it was reported in 2010. Down Syndrome is a common chromosome disorder due to an extra chromosome number 21("PudMedhealth").... [tags: Genetic Disorders]

- Down Syndrome Every parent claims that they will console their newborn with love and affection under any conditions. But inspite of what they may say, they are still worried. After all, there have been several situations with birth defects that have caused years of frusturation and difficulties. No parent wishes for their own child to be born with a genetic mutation, but even as this is true, several children are born with it. “Down syndrome, which is a genetic condition, occurs in one in every 691 births”(Laney 5)....

- Down syndrome, also known as trisomy 21, occurs when a child is born with three copies chromosome 21, as you can see in Figure 1. This can be caused by three different processes; nondisjunction, mosaicism, or translocation. Nondisjunction occurs during the reduction of chromosomes, from 46 to 23, after the egg and sperm have combined, causing one parent to pass on 24 instead of 23. In the case of Down syndrome, the extra chromosome is chromosome 21. Mosaicism is a rare occurrence, happening “in approximately one to two percent of Down syndrome cases” (Johnson, 2013)....

- Down syndrome: A Genetic disorder Each year in the United States, about 13 out of every 10,000 babies are born with Down syndrome, also called trisomy 21 (Johnson). Being the “most common chromosome disorder and genetic cause of intellectual disability”, Down syndrome equally affects males and females as well as all different races (Johnson). In other words, Down syndrome does not show any preference for a specific gender or race. Unfortunately, those who are affected by Down syndrome experience a number of problems throughout their lives which limit their quality of life and health.... [tags: trisomy 21, chromosome disorder]

- Down Syndrome Have you ever been in a situation where you were confronted by a child who has Down Syndrome and were unsure of how to act around that child. I'm sure many of us have experienced the awkwardness that accompanies such a situation. Many people feel guilt or pity for these children, I believe these reactions result from a lack of knowledge about the condition. Which is why I have chosen this topic. Down Syndrome is a condition that cannot be physically passed on from one person to the next.... [tags: essays research papers]

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 condition that affects about one in every one thousand children born around the world....

- 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, 2000)....
