What Is Edwards Syndrome?
8. Risk Factors
In the majority of cases, Edwards syndrome is down to random problems with the formation of eggs and sperm. This makes it difficult to tell who is most at risk, but there are some categories of people that are in a higher risk group. For example, the condition is more likely to occur as the mother gets older.
In a rare number of cases, the condition is inherited. In some instances, not all of the patient’s cells will have the extra chromosome. When this happens it is known as mosaic trisomy, and the symptoms are likely to be less severe than usual.
