Uniparental Disomy
Uniparental Disomy Definition
Uniparental disomy is the situation in which two copies of a chromosome come from the same parent, instead of one copy coming from the mother and one copy coming from the father. Angelman syndrome and Prader-Willi syndrome are examples of disorders caused by uniparental disomy.
