What Is Angelman Syndrome?
Reviewed: Dr. Gromatzky
8. Risk Factors
Angelman syndrome is, thankfully, a very rare condition. Indeed, it is thought to affect only around 1 in every 12,000 to 20,000 people. It is difficult to be sure just how common it really is, however, because in many cases it will go undiagnosed.
We are not sure why the genetic errors occur and we have not yet been able to identify any triggers for the condition. In most cases, there is no history of the condition in the family. However, having family members with the condition can increase somebody’s chance of getting it slightly as it can be inherited in a small number of cases.
