Trisomy 18 Syndrome

Trisomy 18 Syndrome: Introduction

Trisomy 18 Syndrome: A rare genetic chromosomal syndrome where the child has an extra third copy of chromosome 18. Most fetuses are aborted before term, but a live birth with this condition occurs with a frequency around 1-in-3000. Edwards syndrome is more severe than the more common Down syndrome. Edwards syndrome causes mental retardation and numerous physical defects that often cause an early infant death. The condition has variable severity depending on how many of the body's cells have the extra chromosome and how much of the extra chromosome is duplicated. In severe forms all cells have an extra copy of the complete chromosome 18 whereas milder forms may have only some cells having the extra chromosome. Other mild forms may have an extra copy of only part of chromosome 18 in some or all of the body cells. More detailed information about the symptoms, causes, and treatments of Trisomy 18 Syndrome is available below.
