Question -   WHAT IS THE CAUSE AND TYPE OF MUTATION THAT OCCURS TO
CAUSE EDWARDS SYNDROME
-----------------------------
Edward's Syndrome is a trisomy of Chromosome 18, similar to Down's of
Chromosome 21.  Like Patau's it produces physical malformations, mental,
and developmental retardation so severe that most die within a few weeks of
birth.
