Since Edwards syndrome is thought to be caused by a spontaneous
genetic mutation rather than an inherited genetic defect, there is no way
to prevent it. Pregnant women over thirty-five should have tests during
the first trimester (three-month period) of pregnancy to screen for the
syndrome. These tests may involve ultrasound studies, which can detect
abnormalities in the baby’s heart or facial development, followed by a
photographic analysis of cells taken from the fluid that surrounds the
baby in the womb. This analysis, or karyotype, is needed to distinguish
Edwards syndrome from other genetic disorders that can cause heart
defects and facial abnormalities. Doctors recommend that the parents
of a child with Edwards syndrome should consult a genetic counselor for
advice about future pregnancies.
