Down syndrome is one of the most common genetic disorders. Down syndrome is a genetic disorder where a person is born with an extra copy of chromosome 21. Down syndrome is a form of mental retardation. In the United States about 4,000 children are being born with this condition annually. One in about every 900 births is effected, making it the most common birth defect. There are three genetic variations that cause this disorder: trisomy 21, Mosaic Trisomy 21, or Translocation Trisomy 21. There are many ways in how this disorder can affect the body. Trisomy 21 happens when an egg or sperm comes in with an extra copy of chromosome 21, then when an embryo is formed and starts to develop the chromosome is replicated in every single cell of the embryo. Trisomy 21 is …show more content…
Usually if it happens it attaches itself to chromosome 14. About 3-4% of people have Translocation Trisomy down syndrome. Anyone can be born with down syndrome because it is an event that occurs at random. Even though down syndrome can be inherited it usually is not. In the Unites States, about one in every 1000 child born has down syndrome. Down syndrome basically affects all genders and races. There are three different types of down syndrome that have been identified to this day. The first case was reported in the late 1950’s but it was identified as a disorder until the late 1960’s. In about almost all cases it is quite easy to identify a person with down syndrome. It is easy to tell because of the facial features but with the upcoming technology is it making it less noticeable. While there is no cure for this condition there are many treatments and help for the patients to live happy and great lives. Even though these conditions have not been scientifically proven to be 100% effective they have indeed helped many to live more comfortable lives. The medial problems the down syndrome children have

    Edwards syndrome also known as Trisomy 18 occurs in about 1 out of every 2500 pregnancies in the United States alone. This genetic diseases causes severe development delays due to an extra chromosome. Down syndrome is also caused because of an extra chromosome, however the difference between these two is that Edwards syndrome deals with more medical complications and has a higher risk factor on the early months and years of life. It usually occurs during the sperm and egg formation. The disease is rarely inherited and the parents are not at fault for their child obtaining the disease.…

    This trait is not inherited. It usually occurs at random when the reproductive cell of the parent is forming. About 1 in 800 infants are born with Down syndrome. There is also a higher rate of having a child with Down syndrome if the woman has a child at a later age. But saying that since the abnormality is a random occurrence it may still happen at any age of a woman’s…

    This occurs when a pair of the twenty first chromosome in the egg or sperm does not properly divide, resulting in the child having three copies of chromosome 21 instead of just two. The extra copy of chromosome 21 is reproduced in every cell of the unborn child’s body. This type of Down Syndrome is more common than any other type. It is the cause behind 95% of all people with Down syndrome (“Facts about Down Syndrome”).…

    Down's Syndrome is caused by the presence of a single extra chromosome when the sperm cell and ovum join together. The general scientific option is that the extra chromosome produces extra enzymes in excessive quantity. It is believed that the excessive enzymes somehow cause them to interfere with each other and that the developing cells are inefficiently nourished and the bloodstream becomes clogged with the unused nutrients. As a result the organs and tissues do not mature properly. At birth the heart, lungs and brain are malformed and function…

    Incidence and prevalence are terms that can be used to describe a condition. Incidence is the number of new cases, while prevalence is the number of cases reported all together for the specific condition. With changes in today’s society compared to previous time periods, the incidence of Down syndrome has increased. “Down syndrome occurs in about 1 in 800 newborns, about 5,3000 babies are born with Down syndrome in the United States each year, and about 200,000 people in the country who have Down syndrome” (Genetics Home Reference, 2016). Because Down syndrome has become more common, children with Down syndrome are living longer, healthier lives (Centers for Disease Control and Prevention, 2014).…
