Williams Syndrome Foundation

Supporting families living with Williams Syndrome


Williams Syndrome is a rare, randomly occurring genetic condition affecting around 1 in 18,000 people in the UK. It can cause a wide range of challenges, including heart conditions, physical and mental health difficulties, learning disabilities, and sensory, behavioural, social and processing differences.
 
The Williams Syndrome Foundation is the only charity in the UK that supports individuals affected by Williams Syndrome and their families. We provide vital support through funding research, creating resources for parents, carers, healthcare and educational professionals, organising regional family events, and offering respite breaks.
 
We help families stay connected and supported through online support groups, regional events, magazines, social media and our National Family Convention held roughly every three years.
 
As a charity that relies almost entirely on donations and voluntary fundraising, every contribution makes a real difference.
 
With your support, we can continue helping families across the UK navigate the challenges of Williams Syndrome, making sure no one faces it alone.
