Prader-Willi syndrome
A definitive diagnosis of Prader-Willi syndrome (PWS) can usually be made by running a series of genetic tests.
Genetic testing can be used to check the chromosomes in a sample of your child's blood for the genetic abnormalities known to cause Prader-Willi syndrome.
As well as confirming the diagnosis of Prader-Willi syndrome, the results should also allow you to determine the likelihood of having another child with the syndrome.
The checklist can also be helpful for parents concerned about their child's development, behaviour and eating habits, and who want to know whether their child may have Prader-Willi syndrome.
One point is given for each of the following symptoms a child has:
Half a point is given for each of the following symptoms a child has:
If your child is under the age of three and scores five points, with at least three points from the major criteria, Prader-Willi syndrome would be strongly suspected and genetic testing would be recommended.
If your child is over the age of three and scores eight points, with at least four points from the major criteria, Prader-Willi syndrome would be strongly suspected and testing would be recommended.
Prader-Willi syndrome (PWS) is a rare genetic condition that causes a wide range of symptoms including constant hunger, restricted growth and learning difficulites.
Prader-Willi syndrome (PWS) can cause a wide range of symptoms that will affect your child's physical, psychological and behavioural development.
