Overview The genetic basis of Down syndrome. 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.own syndrome is the most common genetic chromosomal disorder and cause of learning disabilities in children. Better understanding of Down syndrome and early interventions can greatly increase the quality of life for children and adults with this disorder and help them live fulfilling lives. 1  Symptoms.

Extracts from this document... Introduction. i»¿ï the, physical, intellectual emotional and social effects on someone With'down s Syndrome down syndrome is a genetic condition where a person inherits an extra copy of one. chromosomet has many effects, for example, it affects people physically, intellectually, emotionally and socially. Individuals living with Down syndrome are affected physically. For example, children with Down syndrome are usually much shorter than other children their ages because they have poor muscle tone.

- Knowledge center. Down syndrome (or Down's syndrome) is a chromosomal disorder caused by an error in cell division that results in an extra 21st chromosome. The condition leads to impairments in both cognitive ability and physical growth that range from mild to moderate developmental disabilities.he only factor known to affect the probability of having a baby with Down syndrome is maternal age. That is, less than one in 1,000 pregnancies for mothers less than 30 years of age results in a baby with Down syndrome. For mothers who are 44 years of age, about 1 in 35 pregnancies results in a baby with Down syndrome.

Down Syndrome Down syndrome is a genetic disorder and the most common autosomal chromosome abnormality in humans, where extra genetic material from chromosome 21 is transferred to a newly formed embryo. These extra genes and DNA cause changes in development of the embryo and fetus resulting in physical and mental abnormalities.

Overview 1 About 95 percent of the time, Down syndrome is caused by trisomy 21 — the child has three copies of chromosome 21 (instead of the usual two copies) in all cells. 2  This is caused by abnormal cell division during the development of the sperm cell or the egg cell.3  Mosaic Down syndrome.t's caused by a mistake in cell division during the development of the egg, sperm or embryo. Translocation Down syndrome is the only form of the disorder that can be passed from parent to child. However, only about 4 percent of children with Down syndrome have translocation.

What gene and chromosome does Down syndrome affect? · just now. Report Abuse. The 21st Chromosome is affected. Down syndrome is a genetic disorder caused by the presence of all or part of an extra 21st chromosome. It is named after John Langdon Down, the British doctor who described it in 1866. The condition is characterized by a combination of major and minor differences in body structure.

What stage of cell division would down's syndrome occur? Down syndrome (trisomy 21) occurs when a gamete carrying an extra copy of chromosome 21 is involved in a fertilization event. The gamete (whether sperm or oocyte) has an extra copy of chromosome 21 because of something called NONDISJUNCTION. This happens when a chromosome gets pulled to the wrong daughter cell.

Difference Between Autism and Down Syndrome Genetic abnormality is the cause of Down syndrome. There are three copies of the chromosome 21 instead of the normal two. Family history of Down syndrome and advanced maternal age increases the risk of Down syndrome in the offspring.

What causes Down syndrome? Research shows that three types of chromosomal changes can lead to Down syndrome. 1  Complete trisomy 21. 2  In this case, an error during the formation of the egg or the sperm results in either one having an extra chromosome. 3  So after the egg and sperm unite, the resulting cells will also have three copies of chromosome 21. The complete extra copy of chromosome 21 is in all of the person's cells—or a complete trisomy. Complete trisomy 21 is the cause of about 95% of Down syndrome cases. Mosaic trisomy 21.

- Chromosomal mutations can have a variety of effects on individuals. Down syndrome is a disorder that causes problems such as mild to moderate mental retardation and slow or stunted development.

What happens to the body when you have Down Syndrome? Please explain! The most common form of Down syndrome is known as Trisomy 21, a condition where individuals have 47 chromosomes in each cell instead of 46. This is caused by an error in cell division called nondisjunction, which leaves a sperm or egg cell with an extra copy of chromosome 21 before or at conception.

- You have probably seen people who have Down syndrome. They have certain physical features, such as a flatter face and upward slanting eyes. They may have medical problems, too, such as heart defects. Kids with Down syndrome usually have trouble learning and are slower to learn how to talk and take care of themselves.

What conditions or disorders are commonly associated with Down syndrome? Blood disorders. Children with Down syndrome are 10 to 15 times more likely than other children to develop leukemia (pronounced loo-KEE-mee-uh), which is cancer of the white blood cells. Children with leukemia should receive appropriate cancer treatment, which may include chemotherapy.

Causes of Down Syndrome These cases are called translocation Down syndrome. Regardless of the genetic variation that is the cause of Down syndrome, people with the disorder have an extra critical portion of chromosome 21 in some or all of their cells. The extra genetic material disrupts the normal course of development, causing Down syndrome symptoms.

- Down syndrome (DS) is a condition in which extra genetic material causes delays in the way a child develops, and often leads to mental retardation. It affects 1 in every 800 babies born. Autism is a complex developmental disorder that appears in the first 3 years of life, although it is sometimes diagnosed much later.

Learning About Down Syndrome 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 the thyroid gland (hypothyroidism) - an organ in the lower neck that produces hormones.
