Thank you to Black Peacock SE, especially David Schwieler, Tommy Westerberg and Lotti Ungerth Fastmarken for all your amazing work on this database. Also to Nathan Durrant and Jennifer Tousseau for all your help on this, the original chart, and many projects. Our deepest thanks to all of The Autoinflammatory Alliance Board of Directors, & to all the patients & families who have supplied images for this chart, & support for the Autoinflammatory Alliance. You are our greatest inspiration and strength!

Great thanks to all of the doctors from the International Society of Systemic Auto-Inflammatory Diseases (ISSAID) for their research & dedication to patients with autoinflammatory diseases, plus the opportunity to present the original chart in a poster session at the Autoinflammation 2013 Congress.

Swedish Orphan Biovitrum AB (Sobi), of Stockholm, Sweden provided the Autoinflammatory Alliance with an unrestricted grant in 2014 to support the development of this Autoinflammatory Search Database to help to educate medical professionals, and a future collection of disease-specific websites for patients. This grant, along with donated funds from the general public and patient community has helped to make this monumental project a reality, and we are so thankful!

Novartis Pharmaceuticals Canada Inc. provided The NOMID Alliance (now known as the Autoinflammatory Alliance) with an unrestricted grant in 2012 to help with the initial development & printing costs for the first comparative chart in print. An unrestricted grant from Swedish Orphan Biovitrum AB (Sobi) in 2013 supported many projects, including: the printing of the final comparative chart that we distributed at the 2013 ACR meeting, and 2014 PRYSM meeting, in addition to mailings to doctors worldwide. The NOMID Alliance has received a number of unrestricted grants at various times from Regeneron, Novartis & Sobi for grant-specific projects.
