Is Prader-Willi Syndrome inherited?

Most cases of Prader-Willi Syndrome are attributed to a spontaneous genetic error that occurs at or near the time of conception for unknown reasons. In a very small percentage of cases (2 percent or less), a genetic mutation that does not affect the parent is passed on to the child, and in these families more than one child may be affected. A Prader-Willi Syndrome-like disorder can also be acquired after birth if the hypothalamic portion of the brain is damaged through injury or surgery. All families with a child diagnosed with Prader-Willi Syndromeshould see a geneticist for genetic counseling in order to fully understand their chances of having another child with Prader-Willi Syndrome.
