The Cause and Effects of Down Syndrome
Some people wonder what Down syndrome is. How it is caused, and how it is treated. The causes and effects of Down syndrome is when there is an extra 21St chromosome. The effects include some birth defects and health problems. The physical features are different from someone without Down syndrome.
What is Down syndrome? It is a chromosomal disorder caused by an error in cell division that results in an extra 21st chromosome (Crosta). Down syndrome causes problems with a person’s physical growth that vary by how bad it is. This disease can develop either before or after a child is born. Less than 1,000 pregnancies for mothers less than 30 years of age result 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 (Crosta). The only way to have a child with Down syndrome is determined by the mother’s age. 75-80% of babies that have Down syndrome are born to younger mothers. It is believed that a younger woman usually has more children verses an older woman (Crosta).
What causes Down syndrome? Robertsonian translocation occurs when part of chromosome 21 breaks off during cell division and attaches to another chromosome (usually chromosome 14) (Crosta). There are 46 chromosomes in the body. 23 are from the mother and 23 are from the father. When there is another copy or a half copies of chromosome 21, you will have a child with Down syndrome. The most common type of Down syndrome is Trisomy 21. It is where the body has 47 Chromosomes instead of 46 (Crosta). Trisomy 21 is caused by a problem in the cell division called non-disjunction; it leaves a sperm or an egg cell with an extra copy of chromosome 21. 95% of Down syndro...

Essay about The Causes and Effects of Down Syndrome

- Down syndrome, also known as trisomy 21, occurs when a child is born with three copies chromosome 21, as you can see in Figure 1. This can be caused by three different processes; nondisjunction, mosaicism, or translocation. Nondisjunction occurs during the reduction of chromosomes, from 46 to 23, after the egg and sperm have combined, causing one parent to pass on 24 instead of 23. In the case of Down syndrome, the extra chromosome is chromosome 21. Mosaicism is a rare occurrence, happening “in approximately one to two percent of Down syndrome cases” (Johnson, 2013)....   [tags: health, disease]
