6. S YMPTOMS OF THE DISORDER Mental retardation Delayed growth development(hands, mouth, etc) Physical malformations such as, odd shaped head and ears. Heart-congenital heart defects (90% of individuals) Clenched hands Crossed legs Malformation of digestive tract. Such as, the intestines.

7. D IAGNOSTIC T ESTING Two types of testing: screening and diagnostic. Screening tests such as a Level 2 Ultrasound indicate a risk, or likelihood that Trisomy 18 is present. These tests take the results of everyone who has had the same testing, and they compare your results with that group. Then they use statistics to identify the odds that it is present in your child, based upon the number of times others with the same test results have had children with Trisomy 18 in the past. Diagnostic tests (karyotype) check actual cells and can determine if Trisomy 18 is actually present. This is a diagnosis, since the condition has actually been found in the cells.

8. P ROGNOSIS The survival rate is very low. Trisomy 18 is considered fatal because most babies die before they are born. Of live born infants, only 50% live up to 2 months, and only 5-10% will survive their first year of life. Major causes of death include apnea and heart abnormalities.

13. A G REAT S TORY Peter is a beautiful boy born with full Trisomy 18. His family found out two days after his birth that he had this condition. Trisomy 18 was described to them as a fatal condition with rare survivors who only live a few weeks. Peter's parents wanted him treated like any other child. Some difficulties arose because of this. Peter has had a P.D.A. ligation, a hernia repair, and a liver biopsy. Peter's family cherishes each day they have with him. They are strongly supported with many prayers from family and friends.
