The Genetic Disorder of Down Syndrome

Chapter 2 had a lot of new information that I was able to learn, a few things that I knew from prior knowledge is that humans take longer to become reproductively mature then any other mammal. I have known this for as long as I can remember with growing up on a farm and watching animals mature. I always thought it was crazy that around the age of 2 could be giving birth to a fully developed baby. Thinking about a two year old child giving birth to a baby would never be possible! Down syndrome is an intellectual disability that is caused by and extra set of chromosomes 21. I’m not sure where I learned this but I have been aware that they are different from you and me because their extra set chromosomes.

Prognosis is another term used in the medical field that explains the outcome or course of a condition. Fortunately, the prognosis of Down syndrome has increasingly been better today than in past years. “The life expectancy for people with Down syndrome has increased substantially” (United Cerebral Palsy, n.d.). In 1929, the average lifespan was nine years old and today it is more common for them to live well beyond the age of 50 years old (United Cerebral Palsy, n.d.). “Many are able to hold jobs, live independently with support and their social functioning often exceeds intellectual functioning” (Gene Facts, n.d.). Because their social functioning is well above the other skills in their lives, many individuals with Down syndrome are form

Many people are affected by genetic disorders every day. Abnormalities in one’s DNA are what cause a genetic disorder. These disorders could be as little as a mutation in a single gene. In another case, they could be as severe as having an extra chromosome, or taking away a chromosome.

Down Syndrome (otherwise called Trisomy 21) is the most widely recognized hereditary issues that causes a long lasting scholarly disability, formative postponements and different issues. Down Syndrome influences individuals of any age, races, and financial levels. It is a standout amongst the most as often as possible happening chromosomal variations from the norm, happening once in each 800 to 1000 live births. More than 350, 000 individuals in the United States alone have Down Syndrome. My objective for this paper is to discuss the three unique sorts of Down Syndrome and to discuss the contrasts between them.

Genetic testing is a medical test that can find and identify changes in proteins, genes or chromosomes. Using a genetic test can confirm or deny a suspected genetic condition, as well as to help determine a person who is possible of carrying on a genetic condition.(NIH, 2016)

With today’s technological advances people should look up a web site, www.ndss.org, specifically for information on people with Down syndrome. In today’s societies a person with Down syndrome still fall into common misconception about who or why they were born Down syndrome. Common misconceptions for a person with Down syndrome consists of them being contagious, they have three of every chromosome, and the umbilical cord wraps around their neck while in the womb. Everyone should mark their calendars for March twenty-first, national world Down syndrome

When first diagnosis was given to Jeremy and his wife there was significant doubt and concern; mostly because of the outdated information presented to the new parents. Finding their own voice and researching on their own they found that Down Syndrome is not the “I’m sorry” they were receiving from friends and family. Down Syndrome changed their lives, but not their love for their daughter. Their daughter, Abigail the “beautiful and lively second-grader is popular, funny and fully included in her classroom.” Abigail = her father’s joy. Something many people are lacking in their lives….joy.

Down Syndrome is a genetic disorder that causes a range of physical disorders and developmental delays. It can be identified by some of the physical attributes the disorder comes with. These include a single deep crease across the palm of the hand, slightly flattened facial profile, and an upward slant to the eyes. To confirm the diagnoses doctors run a karyotype, which is a chromosomal analysis. They do this by extracting a blood sample and grouping chromosomes by size, number and shape.

Down syndrome (known as Trisomy 21) is a genetic disorder caused when cell division results in extra genetic material from chromosome 21. This genetic disorder occurs in about 1 of 800 live births. Down syndrome was first characterized a separate form of mental disability by John Langdon Down in 1862. By the 20th century the disability had become the most recognizable form of mental disability. These individuals have gone through a lot. In ancient times, many infants with this disability were killed or abandoned. The people with Down syndrome used to be called Mongolian idiots and the syndrome was called mongolism. This comes from the people thinking that Down syndrome individuals resembled Mongolians. It doesn’t only affect the individual

It's hard to believe a random error in cell division known as nondisjunction can be the reason for so many birth defects. This one mistake is the cause of 1 in 691 babies being born with what is known as Down Syndrome. In every cell in the human body, there is a nucleus. Typically there are twenty three chromosomes in each nucleus. Down Syndrome occurs when there is extra full or partial copy of chromosome 21. Down Syndrome is a chromosomal condition that causes low muscle tone, small stature, and a single deep crease across the center of the palm. Although, each person with Down Syndrome is a unique individual and may have these characteristics to different degrees.

Down syndrome is a congenital chromosomal disorder during maternal meiosis. This is one of the most common chromosomal disease that has been confirmed (Epstein, 2013). Down syndrome causes some symptoms in children’s physical and mental aspects, which have significant differences with other people. It may cause the life of the child is abnormal and cannot live independently in the future. With the increased population of children with Down syndrome in Australia, it becomes prominent that they strongly impact on their family and society in both positive and negative ways. This article will introduce some basic information about Down syndrome, discuss its early intervention and ethical issues of having a baby with Down syndrome, and result in coming up with views in regards to terminating or continuing with the pregnancy of a foetus diagnosed with Down syndrome.

Down Syndrome, also known a Trisomy 21, is the most common cause of Mental deficiency that occurs from childbirth. Down syndrome is a genetic disorder that occurs when there is an extra chromosome Present. The presence of an extra chromosome causes this genetic disorder because chromosomes contain all of our genetic information and when this information is disrupted during cell division for example, when one is conceived with an added chromosome this causes many problems with the coding of the DNA. down syndrome occurs during cell division in early fetal stages. usually one inherits 23 chromosomes from each parent but in some cases people inherit an extra chromosome and receive three sets of chromosome 21, this is when the genetic disorder

Sometimes, genetic mutations can occur during meiosis. This is a permanent change in the sequence of base pairs in the strand of DNA; in other words, it is a “glitch” in the system. If there is a genetic mutation, it can possibly lead to an extra chromosome, or even the vacancy of one chromosome in the DNA strand. This will result in an organism having a completely extra set of chromosomes. This is the case of Down syndrome, a genetically mutated condition in which a person has 47 chromosomes instead of the usual 46.

Trisomy 21(Down Syndrome) is one of the most common types of chromosomal mutation. First published by John Langdon Down in 1866 and associated with chromosomes in 1959 by Jerome Lejeune, this mutation has affected thousands of infants around the world. The main cause for Down Syndrome is the formation of a 2 chromosome coming together in addition to another that does not belong. This produces extra genetic material. This occurs in the 21st chromosome of a human karyotype and this causes the newborn to have 47 chromosomes instead of the normal 46 chromosomes. So when the egg and the sperm come together there is an uneven amount of chromosomes coming from each parent.

Down syndrome or another name known as trisomy 21 is a genetic disorder that is caused when there is a chromosomal mistake that occurs during meiosis that leaves an extra chromosome. A lot of the time a break occurs in the fourteenth and the twenty first chromosome, this is called Robertsonian Translocation. Breaks can occur in other areas however it seems that Robertsonian Translocation is the most common.
