We’re excited to share research published by community member Larry Schwartz — a statistician who gives his time generously to our Foundation — and a team of researchers at five academic sites in the US and Israel.
This important prevalence study was published in the American Journal of Rare Disorders: Diagnosis and Therapy earlier this summer.
What’s the number?
The team estimates the prevalence of APBD at the gene level (that is, whether the disease is diagnosed or not) at 3,400 for Ashkenazi Jews over 50 years of age in the US.
Why look at Ashkenazi Jews?
APBD is diagnosed far more often among people of Ashkenazi Jewish ancestry.
Why is this prevalence number important?
When a disorder can be shown to affect fewer than 200,000 people in the US, the US FDA applies “Orphan Drug” designation. The designation is tremendously valuable since it expedites the timeline for the FDA to complete its multi-level review of products (drugs, biologics, devices, or medical foods) used to treat rare diseases. It also creates incentives for pharmaceutical companies to develop new products for rare diseases.
Our basic science research is revealing strong contenders for an APBD treatment or cure, and this prevalence study is a part of our preparation for the clinical trials.
Clinical trial readiness — it’s all about you
Your voice matters more than you can imagine! Time and again, we have been advised of the importance of having APBD patients participate in our registry and natural history study initiatives.
News Releases
The APBD Research Foundation is preparing to host a Vision Loss and APBD Focus Group to convene later this fall. This group will bring together APBD patients who have experienced or are experiencing changes to their vision, caregivers, and clinicians in a 1.5 hour session to learn about lived experiences with vision-related symptoms and begin to understand how vision loss is associated with APBD.
The APBD Research Foundation is excited to announce a new collaboration with Costello Medical, Inc., following the Foundation’s successful application to Costello Medical’s pro bono project initiative for Rare Disease organizations.
We are honored to share the story of an extraordinary act of generosity and planning by former Board member David Epstein. David passed away on January 3, 2026.
