We federate the Williams Syndrome organisations and people in Europe

Who we are

The European Federation of Williams Syndrome (FEWS) is the official association of national organisations across Europe which are actively involved in supporting people with the rare genetic condition, Williams Syndrome (WS).

In many European countries, national or local organizations exist in support of Williams Syndrome. These organizations are the FEWS members. Each organization assigns a delegate to represent them within FEWS. FEWS focuses on all items which go beyond the national or local level. Some examples:

  • If any research has been done in one country, the results are shared with the other WS organizations
  • If a WS organization gets a specific question from one of its members, where it has no answer, the question is shared within the FEWS community to find an appropriate answer.
  • Documentation and guidelines are shared and made available for translation in different languages
  • Communication about International WS camps goes through the FEWS delegates
  • The organization of an annual photo contest for and with Williams people

Our goals

  • To spread awareness of Williams Syndrome at the European level, by amplifying the awareness-raising activities of individual national associations.
  • To ensure effective coordination of, and collaboration between national and regional WS organizations in Europe, avoiding the unnecessary duplication of resources.
  • To help direct individuals with WS, as well as their families and carers, to their relevant national or regional associations and to appropriate potential providers of support.
  • To co-ordinate international research efforts by connecting relevant research institutions and professionals with WS organizations.
  • To share and translate relevant publications and guidance materials into the languages of member associations.
  • To organize and participate in international congresses.
  • To promote and manage contact between WS organizations and research institutes outside of Europe.
  • To identify and secure funding to support the organization of leisure and educational camps for individuals with WS from member associations, hosted by volunteer member associations on rotation.

Our ways of working

Each of our member associations supports FEWS by:

  • Participating in FEWS meetings, including by bringing ideas, experiences and ensuring timely follow-up on actions.
  • Attending the yearly AGM meeting and participating in quarterly conference calls.
  • Arranging for timely decisions to be taken by individual member associations where these are required to ratify a decision or recommendation taken by the FEWS board.
  • Sharing resources across the network to avoid duplication of effort or cost, with a particular emphasis on making resources of the larger, more established associations available to the smaller associations.
  • Promptly paying annual membership fees which are tiered depending on the financial standing of each member organization.
  • Continously FEWS has an ePAG (Europen Patient Advocacy Group) representative in ITHACA to ensure a democratic process of patient representation in processes around European Reference Networks (ERNs).

Our achievements in 2025 included:

  • Running our annual FEWS Photo Contest to coincide with the European wide WS Awareness Day, resulting in great engagement on social media. The theme was “Happy Smiles”.
  • Supporting the development of coordinated international clinical guidelines for WS
  • We held our annual general meeting in Lisbon with help and thanks to the Somos Williams, Associação Portuguesa de Síndrome de Williams and the Ordem dos Farmacêuticos.

Our key objectives for 2026 are:

  • Continue to investigate possibilities for providing more camps for cultural exchange.
  • Maintain and strengthen contacts to ITHACA, EURORDIS and with other international organisations.
  • Organise a FEWS photo contest. The theme will be “I can, I shine”. Information on facebook group FEWS Photo Contest 2026.
  • Improve the sharing of research outcomes about WS, including by contributing to international clinical guidelines.
  • Investigating the development of an online knowledge platform for FEWS associations and their members.
  • Encourage and assist the international experts community to make progress on the international guidelines on WS
  • Welcome additional member associations to the FEWS family
  • Continue to encourage members to participate, being a part of the development and to share knowledge for the Waihonapedia for WS, in collaboration with the Nederlandse Vereniging Williams Beuren Syndroom, Netherlands.

Our longer-term aspirations include:

  • Spread knowledge and awareness of Williams syndrome.
  • Continuing to develop active working relationships with other rare disease organisations in order to share experiences, good practices and resources.
  • Securing reliable core funding to support the employment of a staff member that can be a permanent point of liaison for the FEWS member associations and with external bodies such as Eurordis.
  • Living with equality for all persons with WS, everywhere!
