How Common Are Choroid Plexus Cysts?
What is Edwards Syndrome?
Edwards syndrome, or Trisomy 18 , is a rare disorder that happens when the baby has three copies of chromosome 18 instead of the usual 2 copies. Chromosomes are the structures in the cells of your body that are inherited from each of your parents. Chromosomes hold the instructions for how your body looks and functions. Babies with trisomy 18 have severe mental retardation and usually have many birth defects, because of the extra chromosome 18. Only 5% to 10 % of infants survive the first year after delivery. Death is usually caused by inability to maintain normal breathing or heart and lung problems
that are often seen in babies with
trisomy 18 include cleft lip and palate,
jaw, low set ears, club feet, clenched fists, a single umbilical artery , kidney abnormalities,
poor growth, and a high level of amniotic fluid (polyhydramnios) . More
than 90% of babies with
trisomy 18 will have a heart defect.
Amniocentesis may be offered
to you to count and examine the chromosomes of the baby.
Amniocentesis is a test in which a fine needle is inserted into the
uterus , and a sample of the fluid
that surrounds the baby is removed to obtain the baby's cells that
are present the fluid. The chances of amniocentesis causing loss
of the pregnancy (a miscarriage) due to breaking of your water bag or
causing premature labor is about 1 in 300.
