Down Syndrome Research Paper

There are three types of types of Down syndrome, with the most prevalent one being Trisomy 21 (www.ndss.org). The other two are Translocation

Down Syndrome can appear immediately prenatally and postnatally, and has sometimes been shown to have an onset later in life as well. It all depends on the bodies growth over time and

Down Syndrome is a developmental disorder caused by an error in the process of cell division. This disorder is characterized by an extra copy of chromosome 21 (trisomy)(Segal & Pesco, 2015). It is the most common chromosomal disorder and affects 1 in 700 live births (Ramia, Musharrafieh, Khaddage, & Sabri, 2014). According to Segal and Pesco (2015), Down Syndrome is characterised by physical features such as distinct facial characteristics, low muscle tone; conditions such as congenital heart disease; and Intellectual Disability with IQs typically ranging from 30 to 70.

The symptoms of Down Syndrome start to appear when the child is just born. That is when the physical features are seen. The tiny neck, raindrop eyes, flat face, etc. are a huge factor in helping determine if the child is born with Down Syndrome. Some children who are born with this terrible syndrome are born with heart defects. These heart defects can be severe for

Down syndrome is caused by an abnormality with the 21st chromosome. It was first observed by John Langdon Down in 1866. It was not until 1959 that it would be classified as a chromosomal disease by french physician Jérôme Lejeune. According to the article, “Down syndrome occurs when an individual has a full or partial extra copy of

People all over the world are diagnosed with a terrible disease called Down Syndrome. It was discovered by a british physician who was known as Dr. Langdon Down back in 1866 in Britain. This disease causes children to be born with physical and mental abnormalities. With so many children having this disease parents wonder what they have done to cause this curse, but it isn’t their fault. It is simply a random error in cell division which causes an extra copy of chromosome 21. It is mostly inherited at a very young age if not in the womb or after birth. There is no specific treatment for this disease. The only diagnosis for this disease is therapy and help throughout these people's’ everyday lives.

Down syndrome, also known as trisomy 21, is a genetic disorder caused by a third duplicate of chromosome 21. Down syndrome was first recognized as a distinct condition in 1866 by John Langdon Down, after whom the disease is named. Until 1970, the disorder was known as Mongolism and only recently become accepted as “down” syndrome. In 1959, French geneticist Professor Jerome Jejune discovered an extra chromosome to be the cause for the physical and intellectual abnormalities seen in individuals with DS. (Kazemi, Shojaei, & Sadighi, 2016). Down syndrome affects approximately one in every 1200 babies that are born, making it the most common genetic disorder. (Jobling, Virji- Babuls, & Nichols, 2006).

Some symptoms of down syndrome would be that eyes have an upward slant and a whit dot in the iris. There would be a large space between the large and second toe, low muscle tone, and a flat nasal bridge. Also a person with down syndrome would have a protruding tongue, and they would have a small neck and small stature, and they would have a long deep cress on their palm.

Down syndrome was first recognized in medical literature as a distinct disorder in 1862 by John Langdon Down.3 At that time, research in this field was just beginning and individuals with cognitive impairments were not typically differentiated from one another based on medical diagnoses.4 John Langdon Down was the Medical Superintendant of the Royal Earlswood Asylum for Idiots in Redhill, England. The Asylum was among the first to differentiate those with

Symptoms: Common physical symptoms/signs of Down syndrome include. Decreased or poor muscle tone, short neck with excess skin at the back of the neck, flattened facial profile and nose, small head, ears, and mouth, upward slanting eyes, often with a skin fold that comes out from the upper eyelid and covers the inner corner of the eye.

Down Syndrome is a genetic disorder that causes learning disabilities. It’s caused when abnormal cell division results in more genetic material from chromosome 21. This genetic disorder is very common or most occurring. Down Syndrome might cause some health problems. Down Syndrome has only one name and it is Trisomy 21.

Down syndrome, also known as Trisomy 21, was first discovered in 1959 by a French physician named Jérôme Lejeune. He identified down syndrome as a chromosomal condition after noticing that there was a extra copy of chromosome 21 in the individual. Chromosomes are small “packages” of genes that carry hereditary information. They determine how a person will look, how their body functions, and traits they will carry. Normally, the human body contains exactly 46 chromosomes but when down syndrome occurs, the child has 47 chromosomes in the cell.

Down syndrome is a genetic disorder that showcases mental and physical symptoms, where both develop at a slower rate compared to others who do not have Down syndrome. “One of every 700-900 babies born worldwide will have Down syndrome”

Children and adults with Down syndrome have very distinct facial appearances. Babies with Down syndrome may be average sizes at birth, but as they grow you can truly see the delays. They remain smaller than children their age and throughout learning how to crawl and walk it may take them twice as long as children who do not have any disability

To begin ,Down syndrome is a chromosomal disorder that results when a person inherits all or part of an extra copy of chromosome 21. This can occur in a variety of ways, the causes of which are unknown. The most common chromosomal abnormality that produces Down syndrome (accounting for 95% of all cases) is Trisomy 21, a defect in which an extra, third copy chromosome is present in every cell in the body. According to Parenting Magazine the number of Down syndrome births is relatively low for 18-yr-old mothers—1 in about 2100 births. In the later childbearing years the risk in creases—1 in 1000 births for 30-yr-old women to 1 in about 100 births for 40-yr-old women. Two other chromosomal abnormalities cause Down syndrome and occur in about
