What is Prader-Willi syndrome?
Prader-Willi syndrome is a rare genetic condition caused by a chance defect to chromosome 15 at the point of conception. In rare cases, a non-genetic form of Prader-Willi syndrome can also be acquired through injury to the hypothalamus.
Prader-Willi syndrome is usually identified in young children through a symptom checklist, and confirmed through genetic testing. There is no cure for Prader-Willi syndrome, though research is currently trying to find the genes involved in causing it.
Treatment for the feeding issues associated with the syndrome is usually focused on maintaining a healthy diet and exercise, while restricting access to excess food – though this can result in challenging behaviour. Growth hormones can help in mitigating against some of the developmental aspects of the condition.
With appropriate care, people with Prader-Willi syndrome can be supported to achieve the life they want.
Signs of Prader-Willi syndrome
Symptoms can vary, and can affect people to differing degrees. They typically include: –
-
Feeding problems in very early years
-
Constant hunger, leading to a strong desire to eat a lot of food, which in turn can lead to obesity and associated illnesses, such as type 2 diabetes
-
Restricted growth
-
Hypotonia – meaning reduced muscle tone (‘floppyness’)
-
Hypogonadism – meaning lack of sexual development
-
Learning disability, compounded by under-developed emotional and social skills
