Foundation – about us
“We believe that everyone with Koolen-de Vries syndrome should have the chance to develop as well as possible and participate in society.”
We are a foundation committed to people with Koolen-de Vries syndrome (KdVS) and their families. The syndrome is rare. As a result, many healthcare providers, schools and organisations do not yet know it well. Families therefore often have many questions and sometimes have to search for information and help themselves.
Our foundation wants to connect families with each other. We want to offer a place where people can share experiences, knowledge and support. Through contact with other parents and people involved, many families notice that they are not alone.
We also want to spread more knowledge about KdVS. We do this by supporting research, sharing information and working together with healthcare providers and other professionals. We also draw attention to what people with this syndrome need.
In this way we want to contribute to better care, appropriate support and more understanding in society.
Together we build a strong network in which people with KdVS and their families feel supported.
Would you like to contribute? You can support us by donating or taking part in activities. Follow us also on Facebook and Instagram to stay involved and informed about our activities.

What we do
- Connect families with each other.

- Support research, awareness and collaboration.
