Down Syndrome does not only affect the overall life quality of someone with this diesease, but can increase or decrease the chances of that individual from being diagnosed with cancer. Down syndrome, often referred to as DS, is a disease that is has an extra chromosome 21 or HSA21 gene, which causes the number one intellectual disability that is world wide. The child is born with this condition,but DS can be detected before the child is born. Not only does Down Syndrome cause intellectual disabilities,but they can begin physical and medical disabilities as well. People with Down Syndrome have an extra gene on the chromosomes 21 called Trisomy 21 and a third copy of the DSCR1 gene. The DSCR1 gene is also known as the RCAN1 gene which is what …show more content…

Leukemia is an abnormality in the blood where the cancer cells are in the blood,but DS children respond well towards chemotherapies and have a better survival rate. Myelodysplastic syndrome is found in the bone marrow and is pre-cancerous meaning that it more of a chance of becoming cancerous. Myelodysplastic syndrome is when abnormal cells take over the bone marrow and the platelet counts in the red blood cells decrease( Dixion 2-3). Transient myeloproliferative disorder is only found in newborn babies with Down syndrome. This is when the abnormal white blood cells grow rapidly,but only ten to twenty percent of babies develop transient myeloproliferative disorder. This can turn out to be cancerous or non-cancerous either can be present. Treatment varies for different babies and the abnormal cells may go away by themselves and will not need to find the best treatment plan, but no matter what the baby will need to be followed closely to make sure it goes away. WIth the abnormal white blood cells makes the body of someone with DS more prone to leukemia, but the leukemia will not develop in the child until later years( Dixion

    Down Syndrome results when one of the three types of abnormal cell divisions involving chromosome 21 occur. Roger W. Harms, a medical doctor, states, “Human cells normally contain twenty-three pairs of chromosomes. One pair comes from your father and one pair comes from your mother.” In each pair, one chromosome comes from the father, and one comes from the mother. One of the three genetic variations that can cause Down Syndrome is Trisomy 21. This version of Down Syndrome occurs more than 90% of the time. It re...

    Most cases of Down syndrome are not inherited. When the condition is caused by trisomy 21, the chromosomal abnormality occurs as a random event during the formation of reproductive cells in a parent. The abnormality usually occurs in egg cells, but it occasionally occurs in sperm cells. An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. For example, an egg or sperm cell may gain an extra copy of chromosome 21. If one of these atypical reproductive cells contributes to the genetic makeup of a child, the child will have an extra chromosome 21 in each of the body's cells.

    Down Syndrome is a condition that cannot be physically passed on from one person to the next. It is a genetic disorder that is inherited through our parents when something goes wrong during pregnancy. As a result, they have a combination of features typical of Down Syndrome, including some degree of cognitive disability, as well as other developmental delays. One thing we should always keep in mind is that they are children and having Down Syndrome comes second.

    Children born to older parents are at greater risk for genetic abnormalities, such as Down syndrome. No one knows what causes the chromosomal abnormality that results in Down syndrome, a condition according to the National Association for Down syndrome, affects one in 800 to 1,000 babies in the United States. Any woman regardless of her culture, race and socio-economic status can have a baby with Down syndrome. However, a mother’ age seems to be a unifying factor among children with Down syndrome. Older women have a greater chance of giving birth to a baby with Down syndrome, and the risks increases with every passing year. The National Association for Down syndrome estimates the chance of having a baby with Down syndrome to be as follows:

    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 time because they begin to develop a similar disease to Alzheimer’s. “100% of people with Down syndrome will develop some physiologic signs of Alzheimer’s when they are over 35 years old in the U.S” (Statistics about Down Syndrome). They also die earlier because having Down syndrome increases the risk of leukemia 15-20 times in the US. Therefore most people with Downs will die because of leukemia or heart problems before the age of 50.

    Down syndrome, a genetic disorder, is the most common cause for intellectual disabilities, occurring at an average of one out of every 700 births (CDS, 2006). This disorder is caused by the extra chromosome 21 (also known as Trisomy 21). According to Hassold and Sherman (2002), the probability of giving birth to a child with DS is not linked to any race, ethnicity, socioeconomic status or geographic location. Maternal age seems to be the only etiological factor that may cause DS.

    It is a well known fact that all living things, humans included, are made up of cells. The nucleus of a typical cell in the human body is made up of 23 pairs of chromosomes. Half of the pairs come from each parent. In some individuals there is a full 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 the disorder is diagnosed, provide insight of what life is like for a person with Down Syndrome and I will do my best to clear up many misconceptions that people often have about individuals with Down Syndrome.

    Trisomy 21 or more commonly known as down syndrome is a condition in which an individual has a full or partial extra copy of chromosome 21 (What is Down Syndrome?, 2012). It was first described as a disorder in 1866 by doctor John Langdon Down and it is the most common cause of cognitive impairment (Heyn, 2014). Today there are three known types of down syndrome trisomy 21 or called nondisjunction, translocation, and mosaicism. Regardless of the type of down syndrome a child may have, they all have an extra portion of chromosome 21 present and the cause is still unknown today (What is Down Syndrome?, 2012). With the cause unknown many people have misconceptions or don’t understand what down syndrome is. That is why I chose to research down

    In our world today, Down Syndrome, also known as Trisomy 21, is one of the most common genetic conditions. Down Syndrome affects one in every 691 babies each year. Approximately 400,000 Americans have Down Syndrome and around 6,000 babies in the United States are born with it every year (“What is Down Syndrome”). It is very likely for a child with Down Syndrome to develop leukemia in their lifetime. The risk of leukemia is much higher for that of someone with Down Syndrome than it is for someone not affected by Down Syndrome. So, is there some kind of connection between the development of Leukemia in children with Down syndrome?

    The most common type of Down syndrome is Trisomy 21. “Trisomy 21 is an extra chromosome 21 originates in the development of either the sperm or egg.” (4) More than 90 percent of all cases of Down syndrome are Trisomy 21. Another type of Down syndrome is Mosaic Trisomy 21, which is a rare form of Down syndrome and occurs in less than 2 percent of cases. While similar to simple trisomy 21, the difference is that the extra chromosome 21 is present in some, but not all cells, of the individual. “This type of Down syndrome is caused by abnormal cell division after fertilization. The name comes from a random order of normal and abnormal cells (a mosaic). In cellular mosaicism, the mixture can be seen in different cells of the same type; while with tissue mosaicism, one set of cells may have normal chromosomes and another type may have trisomy 21.” (7) Another type is Translocation Trisomy 21. This type happens in 3 to 4 percent of all cases, and is when chromosome 21 becomes attached to another chromosome. “The carrier, the one having the translocated chromosome, will have 45 chromosomes instead of 46 but they will have all the genetic material of a person with 46 chromosomes. This is because the extra chromosome 21 material is located on a different chromosome (the translocated one). A carrier will have the extra material but will have only one chromosome 21. The carrier will not exhibit any of the symptoms of Down syndrome
