In infancy, Prader-Willi syndrome PWS is characterized by weak muscle tone hypotonia , feeding difficulties, poor growth, and delayed development. In later infancy or early childhood, affected children develop an extreme appetite, which leads to overeating and obesity. Showing of View All. Undescended testis. Undescended testes.

Almost all individuals with Prader-Willi syndrome have an abnormality within a specific area of chromosome Genetic testing can confirm the chance that a sibling might be born with Prader-Willi syndrome. Prenatal diagnosis also is available for at-risk pregnancies-that is, pregnancies among women with a family history of Prader-Willi syndrome abnormalities.
Genetic counseling and testing provide individuals and families with information about the nature, inheritance, and implications of genetic disorders so that they can make informed medical and personal decisions about having children. Genetic counseling helps people understand their risks. The risk of occurrence in siblings of patients with Prader-Willi syndrome depends on what caused the disorder to occur.
If your child is under the age of 3 and scores 5 points, and has at least 4 of the major criteria, Prader-Willi syndrome would be strongly suspected and genetic testing would be recommended. If your child is over the age of 3 and scores 8 points, and has at least 5 of the major criteria, Prader-Willi syndrome would be strongly suspected and testing would be recommended.

The inability to control food intake is often the biggest obstacle keeping those with PWS from living independently. To date, no medications have proven effective in regulating appetite in PWS, and therefore, strict environmental control and constant supervision are the only ways to prevent life-threatening overeating and extreme obesity at present.
However, there are a number of novel anti-obesity drugs in clinical development, some of which might benefit the PWS population, and evaluation of these drugs in clinical trials is an important priority for FPWR. In the meantime, a well-balanced diet is recommended Miller Diet , along with careful control of the environment to minimize uncontrolled access to food.
Additional challenges in PWS include sleep disorders, hormone abnormalities, scoliosis, dental issues, and skin picking. Breathing issues during sleep are common and periodic sleep studies are suggested for all ages, including infants. Excessive daytime sleepiness may be improved by the wake-promoting drug, modafinil. This drug also improves cognitive performance and decreases appetite in typical individuals.
Hormone abnormalities common in PWS low thyroid hormones, testosterone, estrogen may be treated by an endocrinologist with standard medications. An overview of endocrine issues for health care providers can be accessed here.
Dental problems also occur frequently in PWS, probably in part due to thicker saliva that is common. You can read about tooth wear and PWS here or learn more by reading our research blog post on oral health.
