Down Syndrome Genetics Abnormality

In the United States, one out of 691 babies is Down Syndrome. (Paragraph 12 of Global Down Syndrome). Abnormalities in the physical and mental characteristics of this hereditary disorder make people diagnosed with life somewhat difficult. Their lifestyle and their parents are more complicated than ordinary people, as they need to pay special attention to their health and education. However, with large-scale medical care and appropriate technology, families can survive the storm. People with Down's syndrome can become fatal due to the large medical complications associated with this disease.

By examining the genetic background of three human diseases: achondroplasia, Wolf Hill Sean syndrome, and Down's syndrome, a relationship between chromosomal abnormalities and phenotypic abnormalities has been shown. Morphological effects of human chromosome (chromosome 13) abnormality were studied in detail. South Africans tell the truth mission. South African government, as part of the settlement by negotiations leading to the election of the termination and the Nelson Mandela of apartheid, in order to investigate the crimes committed in the fight against apartheid from 1960 to 1994, we established the Truth and Reconciliation Commission . As a conclusion of the committee, journalist Bill Moyes and producer and director Gail Perlit reported that they are trying to understand the past "evil not evil" in South African country.

Cri-du-chat syndrome is a very rare disease. Genetologist Jerome Lejeune first discovered the disease in 1963 and furthermore he found genetic abnormalities leading to Down's syndrome. Cri-du-chat syndrome is the result of genetic deletion on the chromosome. It is believed that this disease is the result of a wrong mechanism in the development of eggs and sperm. Surprisingly, in the case of 80%, the missing chromosome is not from the mother's egg but from the father's sperm.

When abnormal cell division involving chromosome 21 occurs, these cell division abnormalities in Down's syndrome result in additional partial or complete chromosomes 21. This additional genetic material is associated with Down's syndrome characteristics and developmental problems Bring. Any of the three genetic mutations may lead to Down's syndrome: Translocation Down Syndrome. Down syndrome also occurs when a part of chromosome 21 adheres (translocates) to another chromosome before conception or during conception. These children usually have two copies of chromosome 2, but they also have another genetic material on chromosome 21 bound to another chromosome.
