March is Trisomy Awareness Month.
Here are some facts about Trisomy 18:
1. Trisomy 18, also known as Edwards syndrome, is a condition which is
caused by a error in cell division, known as meiotic disjunction.
2. Trisomy 18 occurs in about 1 out of every 2500 pregnancies in the United States,
about 1 in 6000 live births. The numbers of total births increase significantly
when stillbirths are factored in that occur in the 2nd and 3rd trimesters of
3. Unlike Down syndrome, which also is caused by a chromosomal defect, the
developmental issues caused by Trisomy 18 are associated with medical
complications that are more potentially life-threatening in the early months
and years of life.
4. 50% of babies who are carried to term will be stillborn, with baby boys
having higher stillbirth rate than baby girls.
