Biorepository: Down Syndrome

We call it our hall of heroes

What is the Down syndrome Biorepository?

BRI’s Down Syndrome Biorepository is a confidential list of people with Down syndrome who are willing to donate samples and provide health information for scientific research.

Nearly half of all People people with Down syndrome also have an autoimmune disease.  BRI’s team is working to learn why. The ultimate goal of this research is to identify new and better therapeutics to prevent and treat autoimmune diseases in people with Down syndrome. Better understanding why autoimmune diseases are more common among people with Down syndrome may also give scientists more insight into how and why autoimmune diseases start in general.

Biorepository donations from individuals with Down syndrome and their family members are invaluable to this work. This information is kept confidential, and samples and health information are coded with numbers, not names.

We are currently enrolling individuals with Down syndrome with and without autoimmune diseases. Our research includes people with:

  • Down syndrome.
  • Down syndrome and Type 1 diabetes.
  • Down syndrome and celiac disease.

We will begin recruiting Down syndrome patients with other autoimmune diseases in the coming months.

We are also enrolling family members of patients with Down syndrome. Those without an autoimmune disease are eligible for the Healthy Volunteer Registry & Biorepository, and those with an autoimmune disease may be eligible for one of our other repositories.

Understanding Immune System Disease in People With Down Syndrome

BRI researchers use our Down Syndrome Biorepository to study:

  • Why having Down syndrome makes a person more likely to develop autoimmune disease.
  • How autoimmune diseases may progress differently in people with Down syndrome.
  • Which therapies might work best to treat immune system diseases in people with Down syndrome.
  • If and how having Down syndrome impacts the effectiveness of vaccines for illnesses like influenza and COVID-19.

Labs Studying Down Syndrome

Khor Lab Main

Khor Lab

The Khor lab is interested in understanding novel pathways that regulate tolerance and inflammation, with the goal of developing novel precision therapies. A major focus of the lab is understanding the mechanistic basis of immune dysregulation in people with Down syndrome.

New Grant Fuels Research Into Preventing Autoimmunity

Naive T cells are like the rookies of your immune system. They’re young and inexperienced. They grow up to do different jobs, most of which help protect your body from viruses and bacteria. But a few stray down the wrong path — growing up to become cells that cause autoimmune disease.

$3.5 Million to Study Down Syndrome and the Immune System

What goes wrong in the immune system that causes autoimmune disease or limits its ability to fight infections? That’s the question Bernard Khor, MD, PhD, started with 12 years ago. His search for answers led him somewhere unexpected: to people with Down syndrome.
