Trisomies consist of the presence of an extra chromosome due to an anomaly in the chromosomal distribution during cell division. Aneuploidies are usually the cause of miscarriage, although sometimes they are compatible with life.
Some examples of trisomies that carry a pregnancy to term are the following:
- Patau syndrome or trisomy of chromosome 13.
- Edward syndrome or trisomy of chromosome 18.
- Down syndrome or trisomy of chromosome 21.
