Most of the time not: Angelman syndrome, while it is a genetic condition, is rarely inherited and thus the risk of it happening again in other children of the same parents is very low, .

Sometimes: Some cases are due to a mutation carried by the mother. Most are due to spontaneous mutations or epigenetic events in the fertilized egg. So, the risk of Angelman may be inherited, but the disease may be genetic or due to epigenetic factors. It is one of the most complex genetic mechanisms yet discovered, and a clinical geneticist must analyze whether other family members are at up to 50% risk
