Down Syndrome Down Syndrome is a chromosomal disorder. It occurs in about 1 of every 800 births. People with Down syndrome may have mild to severe learning disabilities. Physical symptoms include a small skull‚ extra folds of skin under the eyes‚ and a protruding tongue. People with Down syndrome are subject to a variety of medical problems including heart abnormalities and thyroid gland dysfunction. Survival rates have been increased dramatically in recent years as problems specific to Down syndrome

Super Duper® Handy Handouts!™ Number 116 What is Down Syndrome? by Becky L. Spivey‚ M.Ed. What is Down syndrome? Down syndrome is a congenital disorder stemming from a chromosomal abnormality appearing in one of every 800 births. It is the most common genetic disorder affecting more than 5‚000 babies born in the United States each year. This syndrome occurs when one chromosome has an extra “part‚” an error occurs in cell division‚ or an extra chromosome exists resulting in 47 chromosomes. Most

Down Syndrome Although many theories have been developed‚ it is not known what actually causes Down syndrome. Some professionals believe that hormonal abnormalities‚ X-rays‚ viral infections‚ immunologic problems‚ or genetic predisposition may be the cause of the improper cell division resulting in Down syndrome. It has been known for some time that the risk of having a child with Down syndrome increases with advancing age of the mother; i.e.‚ the older the mother‚ the greater the possibility

Down Syndrome (DS) is a chromosomal disease affecting tens of thousands of individuals. DS is responsible for a wide range of health disorders‚ including‚ but not limited to‚ congenital heart disease‚ cancers‚ Alzheimer’s‚ and other phenotypic abnormalities (Asim et al.‚ 2015). Given its relatively high prevalence (1 in 900 births) in some locations‚ the impact of DS is high (Shin et al.‚ 2009). Trisomy 21‚ Mosaic Down Syndrome‚ and Translocation Down Syndrome are three instances of abnormalities

Down Syndrome is a chromosomal condition related to chromosome 21. It affects 1 in 800 to 1 in 1000 born infants. People who have Down Syndrome have learning difficulties‚ mental retardation‚ a different facial appearance‚ and poor muscle tone (hypotonia) in infancy. Individuals with Down Syndrome also have an increased risk for having heart defects‚ digestive problems such as “gastroesophageal reflux or celiac disease”‚ and hearing loss. Some people who have Down Syndrome have “low activity of

Evidence suggests that a very significant proportion of children with Down syndrome could be placed successfully in a mainstream school. Research data‚ although still somewhat limited‚[1] indicates that such placements lead to academic as well as social gains and increase the chances of the child making local friendships that extend beyond the school day. These facts have lead increasing numbers of parents to seek an inclusive placement for their child. In some parts of the country[2] over 80% of

Abstract Down syndrome‚ also known as trisomy 21‚ is the most common chromosome abnormality in humans and it occurs in all races. Approximately 1 of every 691 babies born in the United States each year is born with this genetic condition. Because people with Down syndrome have extra copies of genes on chromosome 21‚ the course of normal development is disrupted and this leads to the distinctive physical characteristics and other health issues that are associated with this syndrome. With appropriate

Down syndrome (Trisomy 21) Down syndrome is a genetic disorder that occurs when an individual has an extra chromosome 21 in them. Down syndrome can also be referred to as ‘Trisomy 21’. An English physician named John Landon Down first discovered Down syndrome back in 1862. This genetic disorder has been around since the 16th century and possibly even longer. The treatments for Down syndrome are not distinct as it depends on how severe the Down syndrome is. Down syndrome or Trisomy 21 was

This disease can affect people drastically‚ or sometimes very little at all. Although there is no way to treat it‚ it can be helped‚ and there are many programs to help. This complex genetic disease is called down syndrome. Down Syndrome has many effects. People with down syndrome usually “look alike.” They usually have

Genetic Project: Down Syndrome What is Down Syndrome? Down Syndrome is a chromosomal disorder where a child is born with an extra partial or full chromosome 21‚ thus leading to the over-expression of many genes present on this extra chromosome. Therefore‚ it is neither dominant nor recessive. Down Syndrome affects about 1 in 700 babies born‚ making it one of the most common genetic birth defects in the United States. There are actually 3 different types of Down Syndrome‚ Trisomy 21 (Nondisjunction)
