Also known as Trisomy 18, Edward's Syndrome is an autosomal disorder. One of the most common, underneath Downs Syndrome.
== This disorder affects the 18th chromosome. It adds extra material creating a third copy instead of the normal two. Most of the time an entire chromosome is copied, but a small percentage of the time only a piece of the chromosome is copied. == ==

__As shown in the picture above, the 18th chromosome has an extra copy.__

‍‍‍‍�
 * == ‍‍‍CLENCHED HANDS ==
 * == SMALL HEAD (Microcephaly)- a condition in which a person's head is signifigantly smaller than expected ==
 * == LOW SET EARS ==
 * == SEVERE MENTAL DEFICIENCY ==
 * == PROMINENT HEEL (rocker-heel) ==

== About 50% of infants with this disorder dont live past the first week of life. In rare cases if they live to teenage years, it is with severe mental retardation and/or physical disabilities. Edward's Syndrome is actually three times more often in girls than in boys. This has nothing to do with the maternal or paternal contributers. ==

**//__ OUTSIDE FACTORS __//**
==** Some tests have shown that geographics can effect trisomy 18. It is more common in babies born into Urban Areas. Also can be more of a seasonal disorder although not many studies have shown testimony to that. The risk of developing Edward's Syndrome can be increased as maternal age increases. **== =__//** Other Facts! **//__=
