What Causes Prader Willi Syndrome?
Prader Willi Syndrome is a rare genetic disorder that occurs in approximately 1 in 15,000 births. The condition is caused by a deletion or loss of function of specific genes on chromosome 15, which typically occurs randomly during the formation of the egg or sperm.
More specifically, the loss of function or deletion of genes on the paternal chromosome 15 leads to the characteristic symptoms of Prader Willi Syndrome. This is because the genes on this chromosomal region are critical for the proper development and function of the hypothalamus, a small but powerful area of the brain that is responsible for regulating various bodily functions.
The hypothalamus plays a crucial role in controlling appetite, metabolism, and the production of hormones that regulate growth and development. In individuals with Prader Willi Syndrome, the dysfunction of the hypothalamus leads to a range of physical and cognitive symptoms, including hyperphagia (increased appetite), low muscle tone, obesity, intellectual disability, and behavioral issues.
Chromosomal Abnormalities and Prader Willi Syndrome
Most cases of Prader Willi Syndrome occur due to a deletion of specific genes on the paternal chromosome 15. However, in some cases, the syndrome can also result from mutations or abnormalities of other genes or chromosomes that affect the same region of the brain as the deleted genes.
In a smaller portion of cases, Prader Willi Syndrome can also occur when both copies of the chromosome 15 are inherited from the mother, rather than one copy from each parent. This is known as maternal uniparental disomy (UPD), and it results in the same gene expression abnormalities as a chromosomal deletion on the paternal chromosome.
Researchers continue to study the underlying genetic mechanisms of Prader Willi Syndrome to better understand its causes and potential treatments.
Recognizing Prader Willi Syndrome Symptoms
Prader Willi Syndrome (PWS) is a complex genetic disorder that can affect multiple aspects of an individual’s physical, cognitive, and emotional development. The symptoms of PWS can vary in severity, but early recognition and diagnosis are crucial in managing the condition effectively.
Some of the common physical characteristics and features of PWS in infants and young children may include:
- Poor muscle tone (hypotonia)
- Feeding difficulties and failure to thrive
- Delayed motor development
- Small hands and feet
- Narrow forehead and almond-shaped eyes
- Low-set ears and a thin upper lip
As individuals with PWS grow older, they may develop symptoms such as:
- Hyperphagia (insatiable appetite)
- Obesity and weight gain
- Delayed puberty and underdeveloped sexual characteristics
- Cognitive challenges, including learning difficulties and developmental delays
- Behavioral issues, such as tantrums, stubbornness, and obsession with food
