**__Edward's Syndrome:__**
====This syndrome, also known as Trisomy 18, is when an autosomal cell has three of the 18th chromosome instead of two. A body's cell ends up having 47 chromosomes instead of 46. Edward's Syndrome is the 2nd most common disease after Down's Syndrome. 95% of the time, a child born with Edward's Syndrome will have a full third chromosome, with the remaining 5% having only a partial 18th chromosome. This syndrome is only found in babies, as the infant dies one or two years after birth. Some even die in the womb. All races and organs of the body are affected.====

__**Symptoms:**__ Survival rate of babies with Edward's Syndrome are low at a 10%.However, the ones that do survive will suffer these symptoms- The deadliest condition of Edward's Syndrom is the Full Trisomy. Unfortunately, 95% of children with Edward's Syndrome have full Trisomy 18. However, a parent with **Translocation Trisomy 18** can survive long enough to born a child with Trisomy 18. Translocation Trisomy 18 is when parts of a third 18th chromosome are scattered in other chromosomes. 2% of Trisomy 18 children have Translocation 18. The parent with TT18 does not show symptoms of the regular Trisomy 18, but will have a high risk of having a child that will. A child can also be born with Mosaic Trisomy 18. Overall in the world, 3% of Trisomy 18 victims have mosaic trisomy. This is not inherited from a parent, and is when only //some// of the child's cells have three 18th chromosomes. People with mosaic Trisomy 18 have lower mortality rates, and can live up to teenage years.

Because it is just a misfortune, there are no outside factors that contribute to this disorder besides previous family cases with the Syndrome.
 * One out of 6600 babies are diagnosed with Trisomy 18.
 * 80% of infants affected by Edward's Syndrome are female.
 * Women over 35 and have past family experiences with Edward's Syndrome have a higher chance of having a child that has Trisomy 18. ||

A doctor can tell before birth that a baby has Edward's Syndrome. The doctor may look for a longer pregnancies, higher amounts of amniotic fluid in the baby, and the lower amount of movement in the baby. The process of testing the amount of amniotic fluid is called amniocentises. ||

**Life Expectancies and Statistics:**

Of the kids diagnosed with Edward's Syndrome:

 * ====50% live less than 2 months====
 * ====90-95% die before their first birthday====
 * 5-10% that survive have problems with body development.
