In infants, signs that may prompt your health care provider to request a blood test for Prader-Willi syndrome include:
- Poor muscle tone and a weak cry
- Poor sucking and feeding problems
- Almond-shaped eyes and narrowing of the head at the temples
- Problems with growth and development
In older children, your child's health care provider may suspect Prader-Willi syndrome if your child exhibits:
- Excessive eating and weight gain
- Underdeveloped sex organs
- Short height and small hands and feet
- Developmental delays
- Intellectual disability
- Thick and sticky saliva
A definitive diagnosis can almost always be made with a lab test. Special genetic tests can identify abnormalities in your child's chromosomes that indicate Prader-Willi syndrome.
