Recurrence risk in the Angelman ("happy puppet") syndrome. American journal of medical genetics. [Am J Med Genet] Journal article

We report on two sibs with Angelman "happy puppet" syndrome. Out of 48 families reported in the literature, this is only the fourth family with affected sibs. A review of the literature shows a low but not negligible recurrence risk. Different explanations for this are discussed.
