Uniparental disomy (UPD), where two copies of genetic material are from one parent, and none from the other, is a familiar cause of imprinting. We present a premature infant with organomegaly and congenital hyperinsulinism found to have complete UPD of paternal origin as determined by Mendelian inheritance error analysis.
单亲二体性（UPD）是一种常见的印记成因，即两份遗传物质均来自一方父母，另一方父母则无。我们报告一例患有器官肿大和先天性高胰岛素血症的早产儿，经孟德尔遗传错误分析确定其为父源完全性单亲二体性。
