Alternative Names:

Edwards syndrome

Prevention:

Prenatal diagnosis of trisomy 18 is possible with an amniocentesis or chorionic villus sampling and chromosome studies on amniotic cells. Parents who have a child with translocational trisomy 18 and want additional children should have chromosome studies, because they are at increased risk to have another child with trisomy 18.
