Understanding Williams Syndrome: Your Path to Genetic Clarity
When you notice developmental delays, unique facial features, or heart concerns in your child, the uncertainty can be overwhelming. Williams Syndrome is a rare genetic condition that affects approximately 1 in 7,500 to 20,000 people worldwide, and early detection through our FISH test provides the answers you need to make informed healthcare decisions for your family.
What Our Williams Syndrome FISH Test Detects
The Fluorescence In Situ Hybridization (FISH) test is a highly specialised genetic screening method that specifically identifies the deletion of genetic material on chromosome 7. This precise deletion causes Williams Syndrome, and our advanced FISH technology provides definitive results with exceptional accuracy. Unlike standard genetic tests, FISH testing offers targeted analysis that directly visualises the specific chromosomal region affected.
Who Should Consider This Important Genetic Screening?
This test is particularly important for families noticing:
- Unexplained developmental delays in infants or young children
- Distinctive facial features including broad forehead, short nose, and full cheeks
- Heart murmurs or cardiovascular concerns detected during paediatric check-ups
- Feeding difficulties and slow weight gain in infancy
- Unusual social personality with extreme friendliness alongside anxiety
- Learning difficulties or intellectual disability concerns
- Family history of genetic conditions or previous children with developmental issues
Why Early Detection Matters for Your Child’s Health
Getting a definitive diagnosis through our Williams Syndrome FISH test provides numerous health benefits:
- Early Intervention Planning: Access specialised therapies and educational support sooner
- Cardiac Monitoring: Proactively manage potential heart conditions common in Williams Syndrome
- Nutritional Guidance: Address feeding challenges and ensure proper growth
- Family Planning: Understand genetic implications for future pregnancies
- Peace of Mind: Replace uncertainty with a clear care pathway
Understanding Your Test Results: Clear Guidance Every Step
Our genetic counsellors provide comprehensive result explanations that are easy to understand. Positive results mean the chromosomal deletion associated with Williams Syndrome was detected, allowing you to immediately connect with appropriate medical specialists. Negative results provide reassurance that your child does not have this specific genetic condition. Either way, you receive the clarity needed to move forward with confidence in your child’s healthcare journey.
