Study population is grouped by controls and PWS. PWS individuals are then further grouped by history of psychosis vs no history of psychosis. Abbreviations: Del deletion, Del I deletion type I, Del II deletion tye II, mUPD maternal uniparental disomy, IC imprinting defect, ns, not specified because no differentiation of specific subtype could be obtained (Del I vs Del II or UPD vs IC) due to different reasons (e.g. no blood from the parents could be obtained).
