Down Syndrome In Children

Improved Essays
Normally a child inherits 46 chromosomes from their parents, 23 from each parent. An abnormal cell division in early embryo development can cause Down syndrome also called Downs Syndrome named from John Langdon Down, an English Physician, who wrote about it in 1866.

A child born with this defect has an extra or abnormal chromosome 21.this changes the way the body and brain develops, and depends on the type of down syndrome and how may cell shave an abnormal chromosome 21.

Experts believe that changes often occur before conception in the woman’s egg and less of ten in the sperm. The type of Down syndrome called trans-location could be passed down through families.

Children with Down syndrome can have fifty different features not everyone

Babies may be later in growth and development for example, rolling over, sitting, standing, walking, and talking. In children, health problems and developmental disabilities may lead to behavioral problems. Teens may face social difficulties and vulnerabilities. They may have a difficult time handling strong emotions and feelings, this can lead to depression and mental health problems. http://www.webmd.com/children/tc/down-syndrome-topic-overview "Down Syndrome - Symptoms, Causes, Diagnosis and Treatment - from WebMD." WebMD. N.p., n.d. Web. 30 Sept. 2015.

There are three types of Down syndrome. Trisomy 21 is the cause of about ninety-five percent of Down syndrome; this is cause by abnormal cell division during development of the egg or sperm cell. Mosaic down syndrome is a rare form of Down syndrome. Some children have some cells with an extra copy of chromosome 21.this mosaic of normal and abnormal cells is caused by abnormal cells is caused by abnormal cell division after the egg is

By the age of thirty-five the chances are one in three hundred and fifty. By forty the chances are one in one hundred and at forty-five the risk is one in thirty percent of giving birth to a baby with Down syndrome.

Having a child with Down syndrome will increase the odds of one in one hundred of having another child with Down syndrome. http://www.mayoclinic.org/diseases-conditions/down-syndrome/basics/causes/con-20020948 "Down Syndrome Causes - Mayo Clinic." Mayo Clinic. N.p., n.d. Web. 30 Sept. 2015.

Children with Down syndrome usually learn and progress more slowly than other children. Not every area of development is affected equally. Specific patterns of cognitive and behavioral features observed among Down syndrome children that differs from normally developed children is the intellectual disability.

Social functions of babies and children with Down syndrome are less delayed as other areas of development. Babies look at faces and smile only about one week later than usual. They are usually quite sociable. Babies enjoy making good use of non-verbal

    When a sort of miscalculation occurs with the fetus’ chromosomes, then they can end up not having enough chromosomes or have too many of them. Down Syndrome is one of the most common birth defects caused by a child having one extra chromosome. Lastly, according to Kids Health, a genetic birth defect can be caused “when both parents pass along a faulty gene for the same disease; this is called recessive inheritance and includes conditions such as Tay-Sachs disease and cystic fibrosis” (par.…

    There are many diseases that affect certain age and gender groups. Tay Sachs is an age specific disease, which is genetically passed down from parent to child. Tay Sachs can be diagnosed as early as 11 weeks into pregnancy using chorionic villi sampling (CVS). If Tay Sachs is not diagnosed before birth, a red spot on the macula, is also an indicator that a child has the genetically fatal disease. Tay Sachs begins to affect infants as early as 3-6 months of age.…

    “Down syndrome is a genetic disorder caused when abnormal cell division results in extra genetic material from chromosome 21. This genetic disorder, which varies in severity, causes lifelong intellectual disability and developmental delays, and in some people it causes health problems. Down syndrome is the most common genetic chromosomal disorder and cause of learning disabilities in children.” ("Down Syndrome - Mayo Clinic") History: Down Syndrome was discovered in 1866 by a British physician named John Langdon Down, which is where the name Down Syndrome came from. This genetic disorder was first referred to as Mongolism. The name Down Syndrome did not start being used until the early 1970s.…

    Down syndrome affects 1 in every 691 births, a condition sometimes called trisomy 21, where a child inherits an extra copy of chromosome 21. Children born with Down syndrome have distinctive features such as: weak muscle tone, a small mouth held partially open because it is not big enough to accommodate for the tongue, and distinguishing eyelids. More serious deficiencies comprise of low resistance to infectious diseases, heart abnormalities, and fluctuating levels of mental retardation, in most cases severe. Information on Down syndrome, including signs, symptoms, and diagnosis; genetic information such as a detailed description on trisomy 21, and translocation; an expanded and comprehensive history on Down syndrome; modern-day individuals…

    Achondroplasia is a form of short-limbed dwarfism which is caused by “failure of endochondral ossification due to a fibroblast growth factor receptor 3 mutation” (Vajo, Francomano, Wilkin, 2000). Some of these dyplasias can potentially be detected on an ultrasound as early as 20 weeks. The measurements the doctors look for on the ultrasound is the length of the humerus or femur. If the length of either of these limbs is less than the fifth percentile it is highly recommended to seek out a specialist. The main concern for fetuses diagnosed with skeletal dysplsia is a small chest circumference which can cause death due to pulmonary insufficiency.…

    There are 3 types of mutations that can be found in the DMD gene and these cause a disruption in the production of dystrophin. The three different types of mutations are large deletions, large duplications and point mutations with other small changes. When large deletions occur, pieces of the DNA are lost. This mutation causes DMD 60-70% of the time. Large duplications causes parts of the DNA to be copied.…

    This is extra genetic material and it is responsible for the developing abnormalities that occur. We have one extra chromosome which is chromosome 21 instead of 46 chromosomes and two sex chromosomes. This phenomenon is called nondisjunction. It happens when a pair of chromosomes fails to separate during egg (or sperm) formation and creates an extra chromosome 21. The extra chromosome is then copied in every cell as the baby develops.…

    Autism is developed during the embryonic stage of development, possibly due to interplay of genetic factors inherited by the parents. Researchers have also found thirteen regions in the genome with chromosomal in unrelated people with autism. These genes may have caused the complexity of the condition. The most significant change was found on chromosome sixteen. In a set of autism cases, researchers discovered abnormalities in several genes known to be involved in neuron function.…

    Background: What is Down Syndrome? Down Syndrome is a chromosomal disorder caused by an error in cell division that results in an extra twenty-first chromosome, that causes birth defects of developmental and intellectual delays. The human body is composed of trillions of cells and within the nucleus of each cell are structures called chromosomes (Parks, 2009). About eight million babies are diagnosed with Down Syndrome in the United States with approximately twenty thousand in Western Europe (Parks, 2009). Down Syndrome affects all races and genders, but lower among non-Hispanic black individuals.…
