Several genetic abnormalities are found in the 15q11-q13 region, including: a de novo interstitial deletion of maternal 15q11-q13 in ~75% of cases (4 Mb deletion), paternal uniparental disomy in 2%, an imprinting center mutation in 2%, and a point mutation in E3 ubiquitin protein ligase gene (UBE3A) in 5-10% [11].
