Congenital Hyperinsulinism International

Million Dollar Bike Ride

2022 Team CHIbra

We are getting Team CHIbra together to raise funds for congenital hyperinsulinism (HI) research at the MDBR – and we need you!

“It took a year to get a diagnosis … It took another year of trial and error to find a treatment plan that worked.” – HI Parent Rebecca

We know how hard it is to live with and manage HI. That is why Team CHIbra is raising funds to address the critical need for research for diagnostic tests that would increase timely diagnosis of HI, tools for better management, new treatments, and one day, a cure.

We hope you can join Team CHIbra in raising HI research funds this year! We are raising these funds as part of the Million Dollar Bike Ride initiative, a project of the Orphan Disease Center of the University of Pennsylvania, our partner in funding research for the past 8 years. They will be matching the first $30,000 of our donations!

To make sure get the fundraising match, we also need volunteers and riders in Philadelphia on Saturday, June 11!

You can sign up to volunteer here:

If you want to ride this fabulous route with the Team (13, 34 or 72 mile routes), you can sign up to ride here *note – online registration deadline is JUNE 5*:

You do not need to fundraise to be a rider – and your registration fee will go straight to our fundraising total! Please mention Congenital Hyperinsulinism International when registering as a volunteer or rider.

And of course, you can donate here:

* You can share our Team CHIbra page with friends and family via email and social media to ask for their support to raise research funds and awareness. Donate $5, $10, $25, or any amount – every gift matters.

* OR click the orange “Start Fundraising” button to the upper right, of the Team CHIbra page, and you’ll be on your way to creating your own 2022 Team CHIbra fundraising page that you can share – you do not need to be a rider or volunteer to create a page. Maximize your fundraising impact and personalize your fundraiser with your stories, photos, and videos. You can manage your fundraiser on your personal fundraising page from start to finish.

Thank you in advance for your support! If you have any questions or need help, email

2021 CHI HI-lights

Dear Friends,
As 2021 draws to a close, we thank you for being part of the CHI community. Thank you for all you do to support the work of CHI, advancing research for better treatments and cures, raising awareness of congenital hyperinsulinism (HI) to prevent brain damage and death, and being there for HI families every step of the way.

Your support helped us have a remarkable year in 2021. Despite the continuing pandemic, there are many reasons for hope and optimism. This has been one of the busiest and most productive years on record for CHI. Click here to look back with us on 2021!

HI Global Registry 2021 Annual Report Now Available

HIGR 3rd Report 2021

The HI Global Registry 2021 Annual Report provides insight into the HI experience as reported by participants of the HI Global Registry (HIGR). 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 analysis and descriptive statistics shared in the report are based on the responses that participants provided from HIGR’s launch in October 2018 through September 2021. This includes individuals living in 46 countries and participants ranging from just a few weeks of age to 60 years old.

The report builds on the previous annual reports released in 2020 and 2019. Additional participation allows for deeper insight into the HI experience, which in time will help provide key data for better diagnostics, HI management, and treatments. We encourage all HI families to join the HI Registry to share your own experience to help provide a more robust and accurate picture of HI.

If you have any questions about the report or HIGR please contact:

CHI announces first group designated as Centers of Excellence

CHI Center of Excellence

The Congenital Hyperinsulinism International (CHI) Hyperinsulinism Centers of Excellence (COE) Program designates centers for providing the highest quality of care for congenital hyperinsulinism (HI) patients and their families around the world.

In June 2021, the first group of centers received the COE designation. This honor recognizes expert centers that provide the highest level of multi-disciplinary care to congenital hyperinsulinism patients and their families and an on-going commitment to research and collaboration.

The CHI COEs are:

  • Congenital Hyperinsulinism Center at the Children’s Hospital of Philadelphia, PA, United States
  • The Hyperinsulinism Center at Cook Children’s Medical Center in Fort Worth, TX, United States
  • Great Ormond Street Hospital Congenital Hyperinsulinism Service in London, in the United Kingdom

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.
