Prader-Willi Syndrome (PWS) is a complex genetic disorder that affects many parts of the body. In newborns, symptoms include weak muscle tone (hypotonia), feeding difficulties, poor growth, and delayed development. As the child grows, other symptoms may emerge, such as an insatiable appetite, leading to chronic overeating (hyperphagia) and obesity. There can also be mild to moderate intellectual impairment and behavioral problems. It’s a rare condition caused by the loss of function of specific genes in chromosome 15.
The diagnosis of Prader-Willi Syndrome is critical for the management and treatment of the condition. One of the most effective diagnostic tools is the FISH (Fluorescence In Situ Hybridization) test, which can confirm the diagnosis by identifying the absence of the paternal copy of chromosome 15, which is responsible for PWS.
Symptoms of Prader-Willi Syndrome
Recognizing the symptoms of Prader-Willi Syndrome is essential for early diagnosis and management. The symptoms are diverse and vary significantly from one individual to another. They include, but are not limited to:
- Weak muscle tone (hypotonia) in infancy
- Difficulty in feeding and poor growth in infancy
- Developmental delays
- Rapid weight gain and obesity from an early age
- Excessive eating and constant hunger (hyperphagia)
- Underdeveloped sex organs
- Behavioral problems, such as temper tantrums and stubbornness
- Mild to moderate intellectual impairment
- Sleep disorders
- Short stature compared to family members
It’s important to note that not all individuals with Prader-Willi Syndrome will have all these symptoms, and the severity can vary widely.
Understanding the FISH Test for Prader-Willi Syndrome
The FISH test is a powerful diagnostic tool used to detect genetic abnormalities associated with Prader-Willi Syndrome. It involves using fluorescent probes that bind to specific parts of chromosomes. For PWS, the test specifically looks for the absence of the paternal copy of genes on chromosome 15. This genetic anomaly is responsible for most cases of Prader-Willi Syndrome.
The accuracy and reliability of the FISH test make it an invaluable step in confirming a diagnosis of PWS. This is particularly important for initiating early intervention programs and management strategies to address the various challenges associated with the syndrome.
Cost of the FISH Test for Prader-Willi Syndrome
In the UAE, the cost of the FISH test for Prader-Willi Syndrome is 1050 AED. It’s a worthwhile investment for families seeking clarity on their child’s condition, as it provides a definitive diagnosis that can guide treatment and management decisions.

Early diagnosis and intervention are crucial in managing Prader-Willi Syndrome effectively. The FISH test is a critical component of the diagnostic process, offering families and healthcare providers the information needed to best support individuals with PWS. If you suspect your child may have symptoms of Prader-Willi Syndrome, consult with a healthcare provider about the possibility of undergoing the FISH test.
With the right care and support, individuals with Prader-Willi Syndrome can lead fulfilling lives. Early diagnosis and a comprehensive understanding of the condition are the first steps toward achieving this goal.
