According to Gould and Dyer (2011), characteristics in people with Down syndrome are typically a small head with a flat facial profile, eyes are slanted and the irises contain a Brushfield spots, mouth tends to hand open, large tongue, and high-arched palate. The person can also have small and a single palmar crease, hypotonic muscles, joints are loose, cervical abnormalities, short stature, delay in developmental stages, sexual development is delayed or incomplete, and children are at risk for other problems such as visual issues, hearing problems, obstructions in the digestive tract, celiac diseas...
The Chromosome Disorder Down Syndrome
Down syndrome is the most common and readily identifiable chromosomal condition associated with mental retardation. It is caused by a chromosomal abnormality: for some unexplained reason, an accident in cell development results in 47 instead of the usual 46 chromosomes. This extra chromosome changes the orderly development of the body and brain. In most cases, the diagnosis of Down syndrome is made according to results from a chromosome test administered shortly after birth.
Approximately 4,000 children with Down syndrome are born in the U.S. each year, or about 1 in every 800 to 1,000 live births.
Translocated Down Syndrome
Translocated Down Syndrome is genetically passed on from a parent’s gene to its child (Clinical Key, 2012). In this paper we will look at a short description of what Down syndrome really is, the genetic causes of Translocated Down syndrome, symptoms, characteristics, medications, intervention programs and testing for Down syndrome while an infant is still in the womb.
The effects of Down syndrome are caused by an extra chromosome. “a genetic disorder, associated with the presence of an extra chromosome 21” (Dictionary.com, 2014).
Down syndrome is a genetic disease where there is an extra chromosome on the 21st chromosome. Now there are three types of Down syndrome Trisomy 21, Mosaic Down syndrome, and Translocation Down syndrome. First we’ll talk about Trisomy 21. According to Mayo Clinic Staff (2011) “More than 90 percent of the time, Down syndrome is caused by trisomy 21. A child with trisomy 21 has three copies of chromosome 21 — instead of the usual two copies — in all of his or her cells.”(Para.3) so from this we can conclude that this is the most common type of Down syndrome. Next there is Mosaic Down syndrome according to the Mayo Clinic Staff (2011) “In this rare form of Down syndrome, children have some cells with an extra copy of chromosome 21. This mosaic of normal and abnormal cells is caused by abnormal cell division after fertilization.” (Para.4) we can conclude from this that this is a rare type of Down syndrome and is a mixture of normal cells and the cells that have more than two chromosomes so it’s like a mosaic because the cells are mixed. Lastly there is Translocation Down syndrome. According to Mayo Clinic Staff (2011) “Down syndrome can also occur when part of chromosome 21 becomes attached (translocated) onto another chromosome, before or at conception. Children with translocation Down syndrome have the usual two copies of chromosome 21, but they also have additional material from chromosome 21 attached to the translocated chromosome. This form of Down syndrome is uncommon.”(Para.5). this paragraph shows that the child has two copies of chromosome 21, but some on one of the copies some extra material sticks on. According to the Mayo Clinic Staff (2011)”Translocation Down syndrome is the only form of the disorder that can be passed fr...
Down syndrome is a chromosomal disorder that occurs when a baby is born with an extra chromosome in each of their cells. It is the most common of the chromosomal disorders. One in every 691 babies is born with DS (Down syndrome) and there are approximately over 400,000 people living with DS in the United States today. Although it is not genetic, it has been proven that mothers older than thirty-five are more likely to have a baby with Down syndrome. Individuals with Down syndrome have varied cognitive delays, meaning that they learn and develop slower than the average person, but they are still able to live normal lives. Many people with Down syndrome attend school, go to work, and are able to have normal relationships, such as marriage.
Down's syndrome is not a disease and therefore people with Down syndrome do not suffer nor are they victims of their condition.Down Syndrome is a natural disorder coming from a chromosome defect. It is a genetic condition in which a person has 47 chromosomes instead of the usual 46. Which causes mental impairment and physical deformity.For example short stature , broad facial profile and weak muscle tone.It occurs in approximately one in every 800 live births.It is the most frequently occurring chromosomal disorder. Down syndrome is not related to race, nationality, religion or socioeconomic status.(medline plus)
Down syndrome is an inherent issue emerging from a chromosome deformity, bringing about scholarly disability and physical variations from the norm including short stature and a wide facial profile. It emerges from a deformity including chromosome 21, for the most part an additional duplicate. Down syndrome may also be known as trisomy 21 due to the fact that that is the chromosome that is affected.
In every cell in the human body, there is a center, where an innate material is secured in qualities.
Human body has autosomes which is normally 23 pairs of chromosomes and allosomes that shows two types of sex. The extra or absent of chromosomes and DNA could cause unusual or uncommon state physically or mentally in human body. Most people who have down syndrome have the abnormality in the number of chromosomes (abnormal situation in autosomes). So the main cause for the down syndrome is absolutely existence of genetic problem.
Down syndrome affects the organ system or body functions. They have a risk of heart defects, respiratory and hearing problems, Alzheimer’s disease, childhood leukemia, epilepsy, and thyroid conditions. Most of Down syndrome is not inherited. When it is caused by trisomy
Many people with Down syndrome suffer from a variety of health problems. The most common and significant symptom is mental retardation, which ranges from mild to moderate. People with Down syndrome suffer from congenital heart defects, which affect approximately 40-50% of these people. Their poor muscle tone makes much physical activity difficult. There are many hormonal problems, mainly thyroid disease. People with Down syndrome suffer from circulatory problems, respiratory ailments, ...
