A Message to the WSA Community On Recent Losses and Sudden Cardiac Death

01/30/2026 - 4:14 pm |

Sarah Schaefer

The Williams syndrome community has faced several heartbreaking events recently, including a number of sudden cardiac deaths. We grieve each person we’ve lost, and we extend our deepest sympathies to their families and loved ones during this profoundly difficult time. 

Many of you have reached out to me directly with your concerns. As the parent of a young adult with Williams syndrome, my son Matthew, I understand how frightening and powerless this feels. Your need for guidance and support is our highest priority.

Taking a deep collective breath and looking at the facts may help steady us. Our medical advisors, including Drs. Barbara Pober, Beth Kozel, Mark Levin, and many others, are among the world’s leading experts in Williams syndrome clinical care and research. They have confirmed that, while several losses have occurred close together, no data currently exists to indicate something new is happening or that there has been a significant increase in the overall number of deaths. However, the possibility of a change in the death rate should be investigated, and the WSA believes systematic inquiry is the most important step in addressing this question. Accordingly, we are working with them, and other WS experts, to ensure that families and clinicians have the most up to date, evidenced-based information available. As soon as our review is completed, the Williams Syndrome Association will release a special report focused specifically on sudden cardiac death in Williams syndrome. This is a complex issue, and our goal is to provide accurate, actionable, and up-to-date guidance for the entire community.

This has long been an area of major WSA commitment. Recently, in partnership with Camille Fortunato and the AGF Research Fund, the WSA invested more than $600,000 in advanced medical equipment to further Dr. Mark Levin’s research in this area. Additionally, the WSA is supporting the Legacy Project through the Collaborative Registry for Williams Syndrome (CReWS), an initiative being led by Dr. Jessican Bowman, which focuses on collecting data regarding death. We are working tirelessly to push this research forward, though it’s important to keep in mind that meaningful research and scientific progress takes time.

Social media amplifies awareness of every loss, whether related to sudden death or not, and we have to be cautious to not allow fear to take hold. What we can do is focus on gathering rigorous, high-quality data to better understand the frequency and causes of these deaths. Careful data collection and systematic review are essential, and this is work the WSA is actively advancing.

If you are looking for immediate steps you can take, I have a few recommendations.

Stay connected to reliable information. Be sure you are a member of the WSA.Membership is free, and it ensures you receive newsletters and updates, which, combined with the website, are the best sources of quality information on Williams syndrome. If you think you’re a member, but you’re not receiving our emails, check your spam or join again!

Enroll in CReWS. Just as important, please enroll your loved one in the Collaborative Registry for Williams Syndrome (CReWS). CreWS, which launched just a few years ago, is a database that collects essential information from both families and the Williams syndrome clinics throughout the US. Data is a cornerstone for moving research forward. If you feel you are enrolled but haven’t been receiving survey emails, please check your junk mail folder for emails with “Collaborative Registry for Williams Syndrome” in the title, or from the email address crews@cumc.columbia.edu. You can also reach out to Michele Disco, the study coordinator, to verify your enrollment.

Verify and communicate. Finally, don’t assume that information shared on social media is complete, accurate, or something the WSA has been monitoring. While social media can be an incredible tool for connection, social posts reflect one person’s experience; they are not vetted medical guidance and should never replace clinical advice or official WSA communications. Whether you have a question, are unsure about work already underway, want to share information we should know, or need accurate, fact-based guidance, please reach out to the WSA.We are here to support you.

We have always described the WSA as a family, and families pull together during difficult times. Our strength comes from supporting one another, sharing what we know, and showing compassion and respect for families mourning the loss of a loved one.

I will continue to provide updates on sudden cardiac death and on the broader research, planning, data-collection, and grief-support efforts that are already underway. If you have questions or concerns, reach out directly: email sarah@williams-syndrome.org, text or call me at 248-509-0060, or contact the WSA office.

Position on Inclusion

The WSA upholds the following positions on inclusion. We believe that: 

  • everyone benefits when individuals with WS are meaningfully included in educational, work, and community settings 
  • individuals with WS should receive all necessary supports and services to fully participate in their family lives, communities, and society as a whole
  • high expectations should be the norm, and individuals with WS and their families should decide how they best learn, work, and enjoy social settings
  • “inclusion” is not one-size-fits-all, and will look different for each family based on each individual’s desires and needs
  • inclusion creates a sense of belonging in society, meaningful relationships, and opportunities to achieve dreams
