February 2024: Take Action to Honor our Journeys on Rare Disease Day


Chip ChambersDear DADA2 Community:

It is Rare Disease Day next week. This is THE time to honor each of our journeys – hard fought and challenging, but unique and inspiring!


Here’s a few stats that I find fascinating, and invigorating!

  • There as many as 9,000 rare diseases identified in the world today, affecting 300 million people.
  • Nearly three-quarters of them are genetic, 70% of those beginning in childhood (similar to DADA2).
  • We know of 600+ DADA2 patients, but studies say 35,000 could be undiagnosed!

This is the challenge before us: let’s find these patients soon, so they can end their diagnostic journey! Our focus is on awareness this Rare Disease Day so that more doctors can diagnose and more patients can get the care they need.

There are many opportunities to support this work and we invite you to take ONE action today. My personal favorite is the new DADA2 Store! Purchase and wear any of these great items as a conversation starter! A percentage of each purchase is donated to the Foundation.

I am so grateful for this community – it’s something many rare diseases don’t have, as is highlighted in comments from our amazing researchers below. Thanks for all you do!

In the Words of a Researcher:
The Benefits of Collaboration

Gathered during our 2023 Scientific Conference

“It’s perfect for us to get together, to get new ideas of how to collaborate on some of these projects.” Dr. Ivona Aksentijevich, USA

“I think that this is an example of how things should be done, that the patients together with the physicians should discuss the disease, should understand the needs of the patients. It’s very important.” Dr. Yackov Berkun, Israel

“The important aspect is, again, the intense collaboration between the basic scientists, medical doctors, experts in developing trials. All of these people have to collaborate all together with the Foundation to really be of help for the patients.” Dr. Marco Gattorno, Italy

“My hope for the future is that we can continue to leverage the collaborations and the fantastic relationship we have among the researchers and also, the patients and their families, to really to be able to solve this puzzle, and it’s a big puzzle.” Dr. Pui Lee, USA
