2022 HI-lights of the Year

We are incredibly grateful that this year brought some of our wonderful congenital hyperinsulinism (HI) community back together, in person, after two years apart, and that we continue to connect virtually with our community across the globe. 2022 has been one of the busiest and most productive years on record for CHI. Let’s look back on our HI-Lights!

2022 CHI Annual Report

The 2022 HIGR Annual Report is here!

CHI and the HI Global Registry (HIGR) team invite you to read the 2022 HIGR Annual Report! The report provides insights into what it is like to have congenital hyperinsulinism (HI) reported by the people who live with it. HIGR is the first global patient-powered congenital hyperinsulinism patient registry and consists of a series of thirteen surveys made up of questions related to a patient’s HI experience over their lifetime. The report builds on previous annual reports that have been shared since 2019. Learn more about the HI Global Registry.

If you have any questions or feedback about the report or HIGR, please contact: [email protected].


It’s time for us to bring the HI Global Registry (HIGR) to the “Max” through an exciting new project, Maximizing the Utilization of the HI Global Registry (MaxHIGR). This project is an international collaboration between leading HI centers and CHI that will add physician-reported data to complement patient-reported responses in the registry. MaxHIGR will help to grow and expand the research possibilities unlocked through HIGR while enhancing the value and impact of the registry.

Any HI patient or caregiver who has completed the relevant HIGR surveys and is interested in participating can now have their physician fill out the MaxHIGR form, which will be returned to them for upload into HIGR. For more information on the project and to learn how you can join, click here!

CHI Collaborative Research Network


A collaborative research network (CRN) is a network of patients and families, physicians, researchers, and patient organizations working together to accelerate research and cures for a particular disease. The CHI CRN builds on the work and momentum of the research done by many experts around the world and our own patient-powered research through the HI Global Registry. The CHI CRN will continue to build on existing projects by forming new partnerships to increase collaboration across institutions and organizations.

CHI receives a Rare As One Network Grant

Chan Zuckerberg Rare As One

Congenital Hyperinsulinism International is thrilled and humbled to announce that we are one of 30 rare disease organizations to receive a Rare As One Network grant of $450,000, distributed over two years, from the Chan Zuckerberg Initiative. This grant will allow us to work with the patient and scientific community to create a patient-led sustainable, lasting structure to prioritize and execute an international research agenda to better understand congenital hyperinsulinism (HI), identify new ways to improve the lives of those living with HI, reduce the incidence of irreversible brain damage, detect the genetic causes of HI types not currently known; and to find cures for each and every type of HI. Over the next few months we will learn much more about the resources available to build the network. We will be in contact with our CHI family partners and the scientific and medical community about collaborating on this exciting project.
