Abstract
Trisomy is a condition in which an extra copy of a chromosome is present in the cell nuclei. Trisomy 18 or Edward’s Syndrome is a chromosomal disorder caused by an extra 18th chromosome. A chromosome is a structure of nucleic acids and proteins found in the nucleus of a cell that carries genes. This extra 18th chromosome can cause major physical abnormalities and severe mental retardation. The extra chromosome is a genetic error resulting from a mistake in egg or sperm formation. If a child is conceived from such an egg or sperm they may inherit an incorrect number of chromosomes. When a child is diagnosed with Edward’s Syndrome there is little chance of a long life. Edward’s Syndrome is usually fatal and most children die young. Edward’s Syndrome has no cure and treatments to help prolong life vary in each case of Trisomy 18. Trisomy 18: Edward’s Syndrome

If you have Trisomy 18 it is also harder to breath and eat. Since people with Trisomy 18 can’t eat as well it’s hard for them to get the necessary nutrients which then leads to stalled growth. It’s hard to live with just one of this symptoms but even harder with all of them. This is why Trisomy 18’s prognosis is so bad.
About 1 in every 5,000 babies is born with Trisomy 18. Trisomy 18 is usually fatal and most babies die before birth. 20%-30% of the children who do survive all the way to birth die in a month. Less than 1% lives for at least a year. A smaller number of people can live many years of life. The mortality rate is so high for Trisomy 18 because there is no

Edward’s Syndrome Edward’s Syndrome, most commonly known as Trisomy 18, is a genetic disorder in which there is an additional copy of material of chromosome 18 (“Trisomy 18: MedlinePlus Medical Encyclopedia,” 2013).

A less common trisomy is known as Edward’s syndrome. (McKinney, James, Murray, Nelson, & Ashwill, 2013). This extra chromosome negatively affects the developmental pattern and has the potential to be life-threatening, even before the baby is born (What is Trisomy 18?, 2015).
