DNA/Tissue Bank &

International Cavernous Angioma Patient Registry

We need everyone's participation!

For several years, Angioma Alliance has operated a DNA/Tissue Bank with a corresponding clinical database. To date, our DNA/Tissue Bank has supported the work of six laboratories and led to the publication of several important papers.


We are now ready to begin the next step. We ask for your participation in the Angioma Alliance International Patient Registry. We will use this resource two ways.

  1. The International Patient Registry will provide a snapshot of the larger community of people affected by cavernous angiomas.  Participants in the International Registry will be able to see this compiled information.
  2. The International Patient Registry will provide a way to contact affected individuals about opportunities for participation in research studies including clinical drug trials.  Participants will have the opportunity to contact researchers themselves to let the researchers know that they are interested in participating in a particular study.

If you are already a member of the DNA/Tissue Bank, you are also encouraged to be part of the International Patient Registry and vice versa. You will need to sign up for each separately. The purpose of the DNA/Tissue Bank is different than that of the International Patient Registry. With the DNA/Tissue Bank, Angioma Alliance collects biological samples and very, very in-depth medical information. Researchers obtain the samples and de-identified information from Angioma Alliance for use in their work. Participants in the DNA/Tissue Bank do not have direct contact with researchers.

 Below is a side-by-side comparison of the two programs.
